Defined in header <math.h>
float       fmaf( float x, float y, float z );
(since C99)
double      fma( double x, double y, double z );
(since C99)
long double fmal( long double x, long double y, long double z );
(since C99)

The fma functions compute (x*y) + z, rounded as one ternary operation, according to the rounding mode characterized by the value of FLT_ROUNDS.

Parameters

x, y, z - floating point values

Return value

(x*y) + z, rounded as one ternary operation
