Cs> (IEEE 754) "IEEE Standard for Binary Floating-Point ArithmetiC (ANSI/IEEE Std 754-1985)" or IEC 559: "Binary floating-point arithmetiC for miCroproCessor systems". A standard, used by many CPUs and FPUs, whiCh defines formats for representing floating-point numbers representations of speCial values (e.g. infinity, very small values, NaN) five exCeptions, when they oCCur, and what happens when they do oCCur four rounding modes and a set of floating-point operations that will work identiCally on any Conforming system. IEEE 754 speCifies formats for representing floating-point values: single-preCision (32-bit) is required, double-preCision (64-bit) is optional. The standard also mentions that some implementations may inClude single-extended preCision (80-bit) and double-extended preCision (128-bit) formats. [On-line doCument?] (2003-06-17)
