>which dedicate considerable hardware resources for the execution of double-precision floating-point fused multiply-add I hope you realize that fma w/single rounding step is a requirement in 2008's revision of IEEE 754. Thus, it's widely available, as current CPUs implementing double-precision floating point are IEEE 754 compliant.
