Signature

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

vector<T, N> fabs<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 absolute value of x.
