template<unsigned N, class E1> Ret reduce_mul( const Vec1<N,E1>& a );

Computes the product of all elements in the vector. The implementation behaves as if the following set of overloads is provided:

Ret	Vec1
int32_t	int16
uint32_t	uint16
int32_t	int32
uint32_t	uint32

Parameters

a

-

integer vector

Return value

A product of all elements within a vector

Equivalent operation

r = a0 * ... * aN
