cospi

Description

Compute the cosine of pi times the input.

Signature

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

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

Generic Parameters

T: __BuiltinFloatingPointType

N : int

Parameters

x : T

The input value.

x : vector<T, N>

The input value.

Return value

The cosine of pi times the input.

Remarks

This function is equivalent to cos(PI*x). On Metal, this function is implemented using the cospi intrinsic.
