mulwide
mulwide(a: UInt32, b: UInt32) -> UInt64
Performs a wide multiplication of two 32-bit unsigned integers.
Multiplies two 32-bit unsigned integers and returns the full 64-bit result. Useful when the product may exceed 32 bits.
Note: On NVIDIA GPUs, this maps directly to the MUL.WIDE.U32 PTX instruction. On others, it performs multiplication using 64-bit casts.
Args:
- a (
UInt32): First 32-bit unsigned integer operand. - b (
UInt32): Second 32-bit unsigned integer operand.
Returns:
UInt64: The full 64-bit product of a * b
mulwide(a: Int32, b: Int32) -> Int64
Performs a wide multiplication of two 32-bit signed integers.
Multiplies two 32-bit signed integers and returns the full 64-bit result. Useful when the product may exceed 32 bits or be negative.
Note: On NVIDIA GPUs, this maps directly to the MUL.WIDE.S32 PTX instruction. On others, it performs multiplication using 64-bit casts.
Args:
Returns:
Int64: The full 64-bit signed product of a * b
