The following functions are used with large integers.
In this section
| Function | Description |
|---|---|
| Int32x32To64 |
Multiplies two signed 32-bit integers, returning a signed 64-bit integer result. |
| Int64ShllMod32 |
Performs a left logical shift operation on an unsigned 64-bit integer value. The function provides improved shifting code for left logical shifts where the shift count is in the range 0-31. |
| Int64ShraMod32 |
Performs a right arithmetic shift operation on a signed 64-bit integer value. The function provides improved shifting code for right arithmetic shifts where the shift count is in the range 0-31. |
| Int64ShrlMod32 |
Performs a right logical shift operation on an unsigned 64-bit integer value. The function provides improved shifting code for right logical shifts where the shift count is in the range 0-31. |
| MulDiv |
Multiplies two 32-bit values and then divides the 64-bit result by a third 32-bit value. |
| Multiply128 |
Multiplies two 64-bit integers to produce a 128-bit integer. |
| MultiplyExtract128 |
Multiplies two 64-bit integers to produce a 128-bit integer, shifts the product to the right by the specified number of bits, and returns the low 64 bits of the result. |
| MultiplyHigh |
Multiplies two 64-bit integers to produce a 128-bit integer and gets the high 64 bits. |
| PopulationCount64 |
Counts the number of one bits (population count) in a 64-bit unsigned integer. |
| ShiftLeft128 |
Shifts 128-bit left. |
| ShiftRight128 |
Shifts 128-bit right. |
| UInt32x32To64 |
Multiplies two unsigned 32-bit integers, returning an unsigned 64-bit integer result. |
| UnsignedMultiply128 |
Multiplies two unsigned 64-bit integers to produce an unsigned 128-bit integer. |
| UnsignedMultiplyExtract128 |
Multiplies two unsigned 64-bit integers to produce an unsigned 128-bit integer, shifts the product to the right by the specified number of bits, and returns the low 64 bits of the result. |
| UnsignedMulitplyHigh |
Multiplies two 64-bit integers to produce a 128-bit integer and gets the high unsigned 64 bits. |
