# Add Unsigned Integer (uint) Support to Operators This skill helps add support for unsigned integer types (uint16, uint32, uint64) to PyTorch operators by updating their AT_DISPATCH macros. ## When to use this skill Use this skill when: - Adding uint16, uint32, or uint64 support to an operator - User mentions "unsigned types", "uint support", "barebones unsigned types" - Enabling support for kUInt16, kUInt32, kUInt64 in kernels - Working with operator implementations that need expanded type coverage ## Quick reference **Add unsigned types to existing dispatch:** ```cpp // Before AT_DISPATCH_V2(dtype, "op", AT_WRAP([&]() { kernel<scalar_t>(); }), AT_EXPAND(AT_ALL_TYPES)); // After (method 1: add unsigned types explicitly) AT_DISPATCH_V2(dtype, "op", AT_WRAP([&]() { kernel<scalar_t>(); }), AT_EXPAND(AT_ALL_TYPES), AT_EXPAND(AT_BAREBONES_UNSIGNED_TYPES)); // After (method 2: use V2 integral types if AT_INTEGRAL_TYPES present) AT_DISPATCH_V2(dtype, "op", AT_WRAP([&]() { kernel<scalar_t>(); }), AT_EXPAND(AT_INTEGRAL_TYPES_V2), AT_EXPAND(AT_FLOATING_TYPES)); ``` ## Type group reference **Unsigned type groups:** - `AT_BAREBONES_UNSIGNED_TYPES`: kUInt16, kUInt32, kUInt64 - `AT_INTEGRAL_TYPES_V2`: AT_INTEGRAL_TYPES + AT_BAREBONES_UNSIGNED_TYPES **Relationship:** ```cpp AT_INTEGRAL_TYPES // kByte, kChar, kInt, kLong, kShort AT_BAREBONES_UNSIGNED_TYPES // kUInt16, kUInt32, kUInt64 AT_INTEGRAL_TYPES_V2 // INTEGRAL_TYPES + BAREBONES_UNSIGNED_TYPES ``` ##
