Scientific Calculator Comparison:CASIO fx-115ES & SHARP EL-W516 Jim Cullen |

Vol I & Vol II are now available for download. See link below.The SHARP EL-W516 and the CASIO fx-115ES represent the best examples of the newest incarnation of the scientific calculator which falls somewhere between the capabilities of the scientific and graphing models currently available. They can be thought of as high-end scientific calculators with some of the capabilities normally found only in the graphing models... without the price-tag typical of a graphing calculator. For a very small investment, students now have the advantage of being able to easily explore the mathematical properties of vectors, matrices, simultaneous equation solving, statistics, complex numbers, and calculus operations such as integrals and derivatives. |

The scientific calculator comparison ( now completed and going through proofreading ) will explore the differences between these two calculators. It is also a user's manual for both calculators and is now available in PDF format. A companion Volume II is also available, containing extra information, tables, applications, and other supplementary material. As of right now, the cost is free. The Scientific Calculator Comparison, in progress being proofread, is available through an account at MediaFire.

Vol I & II are completed and are now available for download. |

The new versions of the SHARP EL-W516B scientific calculator have appeared in major chains such as Target and Sears. The new versions are the EL-W516XB-SL and variants, priced about the same as the EL-W516B. Despite what you might read in some online reviews about a faster processor, new functions, etc., the new versions are the same features as in the EL-W516B except presented in a new package. Speed tests using numerical integration, summation, and everyday functions shows no significant speed increase at all. The physical constants are identical, the same 2006 CODATA values. All numerical algorithms are the same and are the same accuracy as those found in the EL-W516B. The user manuals and example calculations are identical, the function menus identical, and the catalog listing internal to the calculator itself are identical. Side by side, aesthetically, ergonomically, or otherwise, neither has an advantage over the other. The screen pixel size and arrangement are identical, as are the key labels. Both are dual-powered with solar cells and main battery identical. The main differences between the two are entirely cosmetic, evidently a shinier more modern-looking calculator. If this was the goal that SHARP had in mind then they have succeeded, without sacrificing any features or overall usability.

CASIO has released an enhanced version of the fx-115ES scientific calculator, called the
