WebIn computer science, arbitrary-precision arithmetic, also called bignum arithmetic, multiple-precision arithmetic, or sometimes infinite-precision arithmetic, indicates that calculations are performed on numbers whose digits of precision are limited only by the available memory of the host system. WebA fixed-point machine, it can be used to process algorithms traditionally implemented in floating-point math. We discuss the issues that are important in implementing an algorithm in fixed-point math. There are robust procedures for understanding how to do this. We describe useful principles and practices.
