## Beaconaut APICalc 2

Version: 2.0.0.2

Beaconaut APICalc 2 is the leading arbitrary-precision integer calculator in the industry, it's designed for bignum arithmetic and cryptography analysis as well as number theory research for Personal, Academic or Commercial uses. Its speed of bignum arithmetic is dramatically fast with very powerful functionality and easy-to-use like a traditional handheld calculator.

In computer science, arbitrary-precision arithmetic is a technique whereby calculations are performed on numbers whose digits of precision are limited only by the available memory of the host system, It is also called bignum arithmetic, and sometimes even "infinite-precision arithmetic" (which is a misnomer, since the number of digits is both finite and bounded in practice).

Arbitrary precision is used in applications where the speed of arithmetic is not a limiting factor, or where precise results with very large numbers is required.A common application is public-key cryptography (such as that in every modern Web browser), whose algorithms commonly employ arithmetic with integers of hundreds or thousands of digits.Arbitrary precision arithmetic is also used to compute fundamental mathematical constants such as Pi whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. Arbitrary-precision arithmetic can also be used to avoid overflow, which is an inherent limitation of fixed-precision arithmetic.

Bignum math is the backbone of modern computer security algorithms.

Most computer languages provide a kind of data called integer, but such computer integers are usually very limited in size; usually they must be smaller than 2^31 (2,147,483,648). If you want to work with numbers larger than that, you have to use floating-point numbers, which are usually accurate to only six or seven decimal places. Arbitrary precision integer calculators that provide bignums can perform exact calculations on very large numbers, such as 1000! (the factorial of 1000, which is 1000 times 999 times 998 times ... times 2 times 1).
