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

vector<T, N> fmin<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](fmin.html#typeparam-T) The first value to compare. #### y : [T](fmin.html#typeparam-T) The second value to compare. #### x : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The first value to compare. #### y : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The second value to compare. ## Return value The smaller of the two values, element-wise if vector typed. ## Remarks Result is x if x < y, either x or y if both x and y are zeros, otherwise y. Which operand is the result is undefined if one of the operands is a NaN. ## 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. #### spirv Available in all stages.
