--- layout: stdlib-reference --- # distance ## Description Vector distance. Returns the distance between two points. ## Signature

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

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

## Generic Parameters #### T: [\_\_BuiltinFloatingPointType](../interfaces/0_builtinfloatingpointtype-029hm/index.html) #### N : int ## Parameters #### x : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The first point. #### y : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The second point. #### x : [T](distance.html#typeparam-T) The first point. #### y : [T](distance.html#typeparam-T) The second point. ## Return value The distance between x and y. ## Remarks This function is equivalent to length(x-y). When x and y are scalars, this function is equivalent to abs(x-y). ## 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. #### llvm Available in all stages.
