Function subgroup_f_max

pub unsafe fn subgroup_f_max<I: VectorOrScalar<Scalar = impl Float>>(
    value: I,
) -> I

A floating point maximum group operation of all Value operands contributed by active invocations in by group.

Result Type must be a scalar or vector of floating-point type.

Execution is a Scope that identifies the group of invocations affected by this command. It must be Subgroup.

The identity I for Operation is -INF.

The type of Value must be the same as Result Type. The method used to perform the group operation on the contributed Value(s) from active invocations is implementation defined. From the set of Value(s) provided by active invocations within a subgroup, if for any two Values one of them is a NaN, the other is chosen. If all Value(s) that are used by the current invocation are NaN, then the result is an undefined value.

Requires Capability GroupNonUniformArithmetic.
