median3

Description

Median of 3 values.

Signature

T median3<T>(
    T x,
    T y,
    T z)
    where T : __BuiltinFloatingPointType;

vector<T, N> median3<T, int N>(
    vector<T, N> x,
    vector<T, N> y,
    vector<T, N> z)
    where T : __BuiltinFloatingPointType;

Generic Parameters

T: __BuiltinFloatingPointType

N : int

Parameters

x : T

The first value to compare.

y : T

The second value to compare.

z : T

The third value to compare.

x : vector<T, N>

The first value to compare.

y : vector<T, N>

The second value to compare.

z : vector<T, N>

The third value to compare.

Return value

The median of the three values, element-wise if vector typed.

Remarks

For metal, this is implemented with the median3 intrinsic which has special handling for NaN.
