The Sharp EL-W516B was a replacement for my TI-68 that I had for years before it quit. I wish I had switched earlier. The Sharp makes everything I do as an engineer easier. It also cost about half what I paid for the TI. Great value! Great calculator! Great source, Amazon!
Sharp EL-W506 versus Casio FX-115ES September 13, 2008
CECIL ERDLY (FL)
4 out of 4 found this review helpful
I bought a Sharp EL-506R eight years ago because I thought it was the best deal under $20 for a scientific calculator. (I thought the Sharp had been the best deal ever since the EL-506A was introduced.) Then the Casio FX-115MS and FX-115ES (ES) were introduced. Sharp has responded with the EL-W516 (W), so I was anxious to compare it to the similar ES. Both have the entry mode that looks like problems written on paper. Very nice! The following observations are in no particular order.
First the Sharp. I prefer the CHANGE button to the S-D on the ES. It rotates three forms of an answer; mixed number, improper fraction, and decimal.
Arguments for trig and log functions on the W do not require parentheses.
The percent key on the ES no longer does the unique and clever increase, decrease, and change functions as on older Casio models. The W percent is now better.
The W has two more memories (E and F), 4X4 matrices instead of 3X3, 4 matrices rather than 3, and 4 lists rather than 3 vectors.
The W includes pental (base 5) numbers.
The DRILL feature generates quizzes on basic math facts. (Our calculator dependent generation is getting very weak on these!)
Adding vectors in polar form is easier and the display can show the entire answer without scrolling. And changing from rectangular to polar is easier.
The W can do constant calculations with the four basic functions.
It has 4 definable functions and 4 formula memories. These can be used in matrix and list modes.
It has a catalog menu of all functions.
The constants and conversions are stored in the calculator and not on an external list and therefore always available.
The DRG button allows you to convert from degrees to radians, etc. (The DRG button on the ES is completely different; it allows you to enter an angle in degrees while the calculator is in the radian mode, for example.)
The W can store your name so that it is displayed along with the Sharp logo when it is turned off. You can include your telephone number or the name of your favorite nerd on the second line. :-)
The sigma function allows increments other than one. You can add all the odd numbers from 1 to 99, for example, by changing the increment to 2.
The random function includes die, coin, and integer. The die generator, for example, shows numbers one to six.
It is not necessary to specify a separate list for the frequency of data in the STAT mode. It simply requires a comma and the frequency number when it is not one. (This applies to both one and two dimension data.) Also, the associated statistics variables (a, b, r, x', y', etc.) are on the keyboard and easily accessible.
The STO and RCL keys do not require a 2nd function prefix.
Generally speaking, the W requires fewer keystrokes for the frequently used functions. For example, restoring the defaults requires 5 keystrokes on the ES and only 3 on the W.
Now to the Casio. The integral function uses the Gauss-Kronrod method (whatever that is) rather than Simpson's method on the W. It seems faster and more accurate.
The often used ANS and Square Root keys do not require the 2nd prefix.
Results of calculations in different modes can be expressed as exact fractions. Complex numbers can even mix radicals and fractions. Also, complex numbers can be stored in the A-D memories. (The W displays decimals only when not in the normal mode.)
The TABLE function is very handy when you want to view a function over a given domain.
The VECTOR function can actually be duplicated using the LIST function on the W. The W can calculate dot product, cross product, and absolute value using lists as vectors. The VECTOR function is easier to use. However, the W can store complicated formulas, for example, like the angle between vectors and perpendicular vectors, for easily repeated calculations.
The MATRIX and EQUATION functions are nearly identical on the two calculators. I find the ES a little more user friendly on the equation applications. When you modify a matrix or a vector (list), the ES simply uses the data function. The W is rather awkward; it requires a four step process of load, modify, exit, and store. However, it is easier to copy a matrix or list on the W. I wish both the ES and the W would handle matrices and vectors and lists like graphics calculators. They are much more intuitive and easier to remember.
The data used for regression can be saved if you want to try another curve fit. The W erases your data if you decide to try another fit for a better correlation coefficient.
It is possible to generate and find the sum of the terms in an arithmetic or geometric sequence simultaneously using the independent memory. Once initiated, each term only requires one keystroke on the ES. A similar process is possible on the W, but each term requires two keystrokes.
One feature that the ES dropped from the MS model is the copy function. On the older MS model, it was possible to program all the keystrokes necessary to solve the ambiguous case (SSA) by only pressing the equal button. You could view all six results!
I may come back and add to this review as I have longer to live with both calculators. So which one is better? That's a tough question. Both are superior to the HP and TI models in the same price range as far as I am aware. I think nobody would buy these if they knew what the ES and W are capable of. The perfect calculator in this price range would have all the ES and W features with RPN!
The ES is available in many outlets, the W is only available by mail order. I think I prefer the W, but it is close. I would not complain if I had to settle for the ES. If both calculators were available to use, in my subjective humble opinion, I would choose to use the W most of the time. But that may change over time.
Sharp Write View vs Casio Natural Display September 13, 2008
Allen Holmes (Wabasha, MN)

The Casio fx-115 ES and Sharp EL-W516 represent state of the art scientific
calculators for advanced use in statistics, calculus and engineering.
The Casio was my favorite until I got the Sharp. The Sharp excels at statistics and simulation. It has four varieties of random numbers, including dice and coins. I used to teach statistics, pre-calculus, and geometry courses requiring my students to purchase the TI 83 or Casio 975
graphics calculators. If I hadn't retired, I would be requiring them to get the Casio natural display or the Sharp Write View instead. These calculators are as powerful as the graphics versions, but simply cost less and make one use pencil and paper to make the diagrams and graphs. That is educationally sound.
I would recommend teachers buy both of these calculators and let their students choose which one they need. And for statistics, I really recommend the Sharp. One can store formulae in variables F1,- F4, and these may be recalled for rapid analysis of data- such as T-scores and
confidence interval limits.
The Sharp supports lists, while the Casio supports vectors. Lists are
more useful in statistics.
And students will be delighted to spend a fraction of the price of a graphics calculator, and have one which is really portable.
I congratulate Sharp and Casio for engineering such fine, reasonably
priced, superior calculators.
Fabulous and newly improved Sharp El-W506/W516 scientific calculator July 6, 2008
Ann E. Revelle (Los Alamos, New Mexico)

I just purchased the Sharp EL-W506 scientific calculator from the UK at a great low price (from Oxford Educational). However the new Sharp ELW516 now available on Amazon in the USA is apparently ALMOST equivalent to the Sharp EL-W506 (as indicated in the product manual, it is also equivalent to the ELW546). All three nearly identical units have been produced to replace the now discontinued Sharp EL-506WBBK calculator. These are all fabulously improved over the EL-506WBBK and I highly recommend their purchase even in comparison to the Casio FX-115ES (or FX-991ES in Europe) and even over the Casio FX-115ES Plus now available elsewhere.
PROS-
A summary of the most important improvements follows:
a) A catalog is now provided of all functions available within the machine and any of these commands can be stored on the function keys D1-D4 for easy and quick recall.
b) Write-view (Sharp trade mark) 4 line capability for displaying the full set of information on numerical evaluations of integrals and derivatives as well as any other algebraic manipulations. This is totally equivalent to the SVPAM or VPAM available on the Casio FX-115ES or ES Plus, etc.
c) A "Change" key to convert from Decimal to fractional forms and back again which is very similar to what is also found on the respective Casio machines.
d) Full control over the keyboard contrast is also now available.
e) 556 functions are claimed to be available on the new Sharp units as compared to a little over 400 on the FX-115ES (417 functions are claimed on the new FX-115ES Plus). There are also six modes that can be set to work within such as: Normal for integration, ordinary number crunching, etc., Complex numbers, Matrices, Lists, Equation solving, etc.
f) An on-screen form to be filled in is available for full and easy storage of all lists, matrices and vectors. Matrices are also easily manipulated into lists.
g) There is also a much improved set of information provided during the process of obtaining scientific constants and for the conversion of metric values to non-metric unit values as well.
h) Frequently used expressions that you are free to create are quickly and easily stored on the special keys F1-F4 for repeating computations. These same keys (unshifted) can also be used for a very useful multi-line playback of results as well. There are also separate D1-D4 keys (directly above the F1-F4 keys) for memory and expression storage as well giving the Sharp a large number of memory locations.
i) When the calculator turns off after 10 minutes of inactivity, the display resumes to indicate your results exactly where you left off and all work is NOT lost into cyberspace! This feature the Casio will not perform as all work is lost when the Casio is turned off!
j) Statistical functions are also input more intuitively and conveniently (arrangements have been changed on the keyboard) than on the EL-506WBBK as well (A set of up to 100 values can be input for 2 parameter statistics). All of the one parameter {x} and two parameter {x,y} statistical data (each separately specified with frequency of occurrence information) are also readily available on-screen with the touch of the central up-down, left-right control key, both before and after their entry for editing, etc. Unlike the Casio FX-115ES calculator which then consolidates the statistics calculations into a single isolated menu accessed from the keyboard, the Sharp has numerous specified keys shifted through the alpha key prompt to access all statistical results which makes its keyboard somewhat busy compared to the Casio, but still very useful and well organized.
k) The solutions displayed for both cubic and quadratic equations are now in a much more readable form as well as for the two and three values linear equation solutions.
l) A name or lengthy phrase with embedded spaces can also be readily stored deep within the machine that is automatically displayed with the Sharp Logo during the shutdown process. I believe that this new feature will tend to cut down on theft problems too.
m) The new EL-W506/516/546 now requires only a single LR44 backup battery unlike the EL-506WBBK which required 2 of these batteries.
n) Even after all this, its size hasn't changed at all and the new Sharps can still evaluate up to 4th order matrices whereas the Casio will only evaluate matrices as high as 3rd order!
o) The newly revised MATH menu is an excellent control feature for doing various operations within various modes as is the SET-UP control menu shifted on the same key.
CONS:
a) Numerical integrals on the new Sharp units are now a little slower to perform than on the Casio FX-115ES for example, but once complicated integrals are performed the time differences are much smaller.
Finally, in this global world of ours, I wish that both Sharp as well as Casio would do a better job of providing more reliable and truthful information not only to us the end users, but also to its N. American employees on the distribution to N. America of all of its various new products.
