--- layout: stdlib-reference --- # reversebits ## Description Reverse order of bits. ## Signature

T reversebits<T>(T value)
    where T : __BuiltinIntegerType;

vector<T, N> reversebits<T, int N>(vector<T, N> value)
    where T : __BuiltinIntegerType;

## Generic Parameters #### T: [\_\_BuiltinIntegerType](../interfaces/0_builtinintegertype-029g/index.html) #### N : int ## Parameters #### value : [T](reversebits.html#typeparam-T) The value to reverse bits of. #### value : [vector](../types/vector/index.html)\<[T](../types/vector/index.html#typeparam-T), [N](../types/vector/index.html#decl-N)\> The value to reverse bits of. ## Return value The bits of value, reversed such that bit n of the result is equal to bit (width - 1 - n) of value. ## Remarks For SPIR-V, this function maps to OpBitReverse. ## 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.
