template<unsigned N, class E> Ret<N, _DETAIL_> round( Vec<N,E> a );

Rounds the values in a floating-point vector towards nearest integer value. The implementation behaves as if the following set of overloads is provided:

Ret	Vec
float32	float32
float64	float64

The return type is a vector expression.

Parameters

a

-

floating-point vector

Return value

A vector expression evaluating to round(a).

Equivalent operation

r0 = round(a0)
...
rN = round(aN)
