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

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

## Generic Parameters #### T: [\_\_BuiltinFloatingPointType](../interfaces/0_builtinfloatingpointtype-029hm/index.html) #### N : int ## Parameters #### x : [T](powr.html#typeparam-T) The base value, must be >= 0. #### y : [T](powr.html#typeparam-T) The exponent value. #### x : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The base value, must be >= 0. #### y : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The exponent value. ## Return value The value of x raised to the power of y. ## Remarks Return value is undefined for non-positive values of x. ## Availability and Requirements Defined for the following targets: #### hlsl Available in all stages. #### glsl Available in all stages. #### cpp Available in all stages. #### cuda Available in all stages. #### metal Available in all stages. #### wgsl Available in all stages. #### spirv Available in all stages.
