Keisan Covers Practically Every Calculation Need

Casio Provides Site with High Precision Calculation Tools for Science, Mathematics, and Daily Life

Dover, NJ. — Casio Computer Co., Ltd., announced today the official launch of an English Version of its high precision calculation website, “Keisαn,” which means “calculation” in Japanese.

Keisαn provides a free online service that allows users to perform a variety of calculations, and is designed to give back to society the expertise in calculation that Casio has developed over many years as a calculator manufacturer. In order to provide users with consistently reliable results, the site is intended to offer calculation with guaranteed accuracy using Casio’s own arithmetic operation system with a variable number of digits.*

The Library page on the site offers a wide variety of libraries including operations necessary for serious mathematics such as Bessel functions and probability functions; as well as features useful in everyday life, such as measurement unit converters, loan calculators and calendar-related tools. The recommended calculation library section on the right side of the menu includes features like sunrise and sunset times, same birthday probability and other unique formulas. The website provides visitors with a number of fun, convenient calculation features.

The Japanese version of the website was launched in April of last year and is already receiving an average of 150,000 visitors each day. The site was met with favorable reaction as a calculation site that is both entertaining and practical. Now, with the launch of the English version of the site, an even greater number of people are able to benefit from Casio’s highly accurate calculation tools.

The content of the website will continue to be enhanced in the pursuit of the accuracy, usability and greater enjoyment of the calculation features.

*Calculation with guaranteed accuracy based on an arithmetic operation system with a variable number of digits.

Through the adoption of a calculation system allowing selection of the number of digits used for calculation, users are able to set the number of digits, up to a maximum of 50 digits. The system performs each calculation with the user-selected number of digits, and then again with a greater number of digits internally, to compare the two results. The range defined by both results is displayed as the guaranteed accuracy range.
