FMA(3)			 BSD Library Functions Manual			FMA(3)

NAME
     fma — multiply and add, then round

SYNOPSIS
     #include <math.h>

     double
     fma(double x, double y, double z);

     float
     fmaf(float x, float y, double z);

DESCRIPTION
     The fma() and fmaf() functions compute (x*y)+z, rounded as one ternary
     operation: they compute the value (as if) to infinite precision and round
     once to the result format, according to the current rounding mode.

SPECIAL VALUES
     fma(x, y, z) returns a NaN and optionally raises the "invalid" floating-
     point exception if one of x and y is infinite, the other is 0, and z is a
     NaN.

     fma(x, y, z) returns a NaN and raises the "invalid" floating-point excep‐
     tion if one of x and y is infinite, the other is 0, and z is not NaN.

     fma(x, y, z) returns a NaN and raises the "invalid" floating-point excep‐
     tion if x times y is an exact infinity, and z is also an infinity but
     with the opposite sign.

SEE ALSO
     fdim(3), fmax(3), fmin(3)

STANDARDS
     The fma() and fmaf() functions conform to ISO/IEC 9899:1999(E).
