Description

Round-to-nearest.

Signature

T round<T>(T x)
    where T : __BuiltinFloatingPointType;

vector<T, N> round<T, N:int>(vector<T, N> x)
    where T : __BuiltinFloatingPointType;

matrix<T, N, M> round<T, N:int, M:int>(matrix<T, N, M> x)
    where T : __BuiltinFloatingPointType;

Generic Parameters

T: __BuiltinFloatingPointType

N : int

M : int

Parameters

x : T

The value to round.

x : vector<T, N>

The value to round.

x : matrix<T, N, M>

The value to round.

Return value

The value rounded to the nearest integer.

Remarks
