fmax3

Description

Floating-point maximum of 3 inputs.

Signature

T fmax3<T>(
    T x,
    T y,
    T z)
    where T : __BuiltinFloatingPointType;

vector<T, N> fmax3<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 largest of the three values, element-wise if vector typed.

Remarks

If any operand in the 3-way comparison is NaN, it is undefined which operand is returned.
