fmax

Description

Floating-point maximum considering NaN.

Signature

T fmax<T>(
    T x,
    T y)
    where T : __BuiltinFloatingPointType;

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

Generic Parameters

T: __BuiltinFloatingPointType

N : int

Parameters

x : T

The first value to compare.

y : T

The second value to compare.

x : vector<T, N>

The first value to compare.

y : vector<T, N>

The second value to compare.

Return value

The larger of the two values, element-wise if vector typed, considering NaN.

Remarks

For metal, if either value is NaN, the other value is returned. If both values are NaN, NaN is returned. For other targets, if x is NaN, y is returned, otherwise the larger of x and y is returned.
