Mojo function
mulhi
def mulhi(a: UInt16, b: UInt16) -> UInt32
Calculates the most significant 32 bits of the product of two 16-bit unsigned integers.
Multiplies two 16-bit unsigned integers and returns the high 32 bits of their product. Useful for fixed-point arithmetic and overflow detection.
Note: On NVIDIA GPUs, this maps directly to the MULHI.U16 PTX instruction. On others, it performs multiplication using 32-bit arithmetic.
Args:
- a (
UInt16): First 16-bit unsigned integer operand. - b (
UInt16): Second 16-bit unsigned integer operand.
Returns:
UInt32: The high 32 bits of the product a * b
def mulhi(a: Int16, b: Int16) -> Int32
Calculates the most significant 32 bits of the product of two 16-bit signed integers.
Multiplies two 16-bit signed integers and returns the high 32 bits of their product. Useful for fixed-point arithmetic and overflow detection.
Note: On NVIDIA GPUs, this maps directly to the MULHI.S16 PTX instruction. On others, it performs multiplication using 32-bit arithmetic.
Args:
- a (
Int16): First 16-bit signed integer operand. - b (
Int16): Second 16-bit signed integer operand.
Returns:
Int32: The high 32 bits of the product a * b
def mulhi(a: UInt32, b: UInt32) -> UInt32
Calculates the most significant 32 bits of the product of two 32-bit unsigned integers.
Multiplies two 32-bit unsigned integers and returns the high 32 bits of their product. Useful for fixed-point arithmetic and overflow detection.
Note: On NVIDIA GPUs, this maps directly to the MULHI.U32 PTX instruction. On others, it performs multiplication using 64-bit arithmetic.
Args:
- a (
UInt32): First 32-bit unsigned integer operand. - b (
UInt32): Second 32-bit unsigned integer operand.
Returns:
UInt32: The high 32 bits of the product a * b
def mulhi(a: Int32, b: Int32) -> Int32
Calculates the most significant 32 bits of the product of two 32-bit signed integers.
Multiplies two 32-bit signed integers and returns the high 32 bits of their product. Useful for fixed-point arithmetic and overflow detection.
Note: On NVIDIA GPUs, this maps directly to the MULHI.S32 PTX instruction. On others, it performs multiplication using 64-bit arithmetic.
Args:
Returns:
Int32: The high 32 bits of the product a * b
def mulhi(a: UInt64, b: UInt64) -> UInt64
Calculates the most significant 64 bits of the product of two 64-bit unsigned integers.
Multiplies two 64-bit unsigned integers and returns the high 64 bits of their product. Useful for fixed-point arithmetic and overflow detection.
Note: On NVIDIA GPUs, this maps directly to the MULHI.U64 PTX instruction. On others, it performs multiplication using 128-bit arithmetic.
Args:
- a (
UInt64): First 64-bit unsigned integer operand. - b (
UInt64): Second 64-bit unsigned integer operand.
Returns:
UInt64: The high 64 bits of the product a * b.
