template<typename Tc , require_arithmetic_t< Tc > * = nullptr>

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

inline

The fused multiply-add function for two variables and a value (C99).

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

The partial derivatives are

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

$\frac{\partial}{\partial y} (x * y) + z = x$.

Template Parameters

Tc	type of the summand

Parameters

x	First multiplicand.
y	Second multiplicand.
z	Summand.

Returns

Product of the multiplicands plus the summand, ($a * $b) + $c.
