NVIDIA Fermi Architecture Whitepaper
www.nvidia.compoint unit (FPU). Prior GPUs used IEEE 754-1985 floating point arithmetic. The Fermi architecture implements the new IEEE 754-2008 floating-point standard, providing the fused multiply-add (FMA) instruction for both single and double precision arithmetic. FMA improves over a multiply-add (MAD) instruction by doing the multiplication and

sites.pitt.eduConverting an IEEE 754 number to decimal The decimal value of an IEEE number is given by the formula: (1 -2s) *(1 + f) *2 e-bias Here, the s, f and e fields are assumed to be in decimal. – (1 -2s) is 1 or -1, depending on whether the sign bit is 0 or 1. – We add an implicit 1 to the fraction field f, as mentioned earlier. –
