SANE (Standard Apple Numerics Environment) is a fast IEEE-754-compliant math library written in 6502/65C816/68000 assembly language.
The Amiga came with IEEE software FP plus a second math library using Motorola's Fast Floating Point (FFP) format. Later 680x0 CPUs had optional IEEE-754-compliant FPUs, then the 68040 had an integrated FPU but slightly cut down from the external 68881/68882 FPUs. Transcendental routines such as trig functions requiring lookup tables removed, things like that.
