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. –
NVIDIA Fermi Architecture Whitepaper

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

www.xilinx.comSee IEEE-754 Standard [Ref 1] and PG060, LogiCORE IP Floating-Point Operator v6.1 Product Guide[Ref 2] for more details. Some simple, but compelling, software examples are offered here to motivate attention to Validating the Results of Floating-Point Calculations . Example 1 demonstrates that different methods (and even what appears to be the same
Floating-Point Operator v7 - Xilinx
www.xilinx.comThe IEEE-754 Standard requires provision of Signaling and Quiet NaNs. However, the Xilinx Floating-Point Operator core treats all NaNs as Quiet NaNs. When any NaN is supplied as one of the operands to the core, the result is a Quiet NaN, and an invalid operation
