var stan::math::fma ( Ta &&  x, const var &  y, Tc &&  z  )

inline

The fused multiply-add function for a value, variable, and value (C99).

This function returns the product of the first two arguments plus the third argument.

The derivative is

\(\frac{d}{d y} (x * y) + z = x\), and

Template Parameters

Ta	type of the first multiplicand
Tc	type of the summand

Parameters

y	Second multiplicand.
z	Summand.
