[issue29282] Fused multiply-add: proposal to add math.fma()

[Mark Dickinson]

Mark Dickinson added the comment:

The patch needs tests for the case where a*b overflows and c is infinite (either of the same sign as a*b or not). This combination should never return NaN, but a poor emulation of fma might do so.
