fma Function
Computes the product of the first and second specified arguments, then adds the third specified argument to the result; the entire computation is performed as a single operation.
inline float fma(
float _X,
float _Y,
float _Z
) restrict(amp);
inline double fma(
double _X,
double _Y,
double _Z
) restrict(amp);
Parameters
_X
The first floating-point argument._Y
The second floating-point argument._Z
The third floating-point argument.
Return Value
The result of the expression (_X * _Y) + _Z. The entire computation is performed as a single operation; that is, the sub-expressions are calculated to infinite precision, and only the final result is rounded.
