{{Floating-point}}
In [[computer science]], '''arbitrary-precision arithmetic''', also called '''bignum arithmetic''', '''multiple-precision arithmetic''', or sometimes '''infinite-precision arithmetic''', indicates that [[calculation]]s are performed on numbers whose [[numerical digit|digits]] of [[precision (arithmetic)|precision]] are potentially limited only by the available [[memory (computers)|memory]] of the host system. This contrasts with the faster [[fixed-precision arithmetic]] found in most [[arithmetic logic unit]] (ALU) hardware, which typically offers between 8 and 64 [[bit]]s of precision.
