Overview

The module provides hardware-accelerated operations for numeric data types.

BitOperations Class

BitOperations class provides bit manipulation operations for unsigned integer values of 32 and 64 bit lengths. The main consumers of hardware-accelerated bit operations are path-finding and cryptographic algorithms.

BitOperations class is a polyfill to the future as it first appeared in .NET Core 3.0.

Log2

BitOperations.Log2 method calculates the integer base 2 logarithm of a specified number. Log2(0) returns an undefined value since such operation is undefined.

The behavior corresponds to BSR instruction from Intel x86 instruction set.

PopCount

BitOperations.PopCount method calculates the bit population count for a specified value. The result corresponds to the number of bits set to 1.

The behavior corresponds to POPCNT instruction from Intel x86 instruction set.

RotateLeft

BitOperations.RotateLeft method rotates the specified value left by the specified number of bits.

The behavior corresponds to ROL instruction from Intel x86 instruction set.

RotateRight

BitOperations.RotateRight method rotates the specified value right by the specified number of bits.

The behavior corresponds to ROR instruction from Intel x86 instruction set.

BitOperationsEx Class

BitOperationsEx class provides an extended set of bit-twidling operations that are not in mainstream .NET yet.

Reverse

BitOperationsEx.Reverse method reverses the order of bits in a specified value and returns a result. The least significant bit gets swapped with the most significant bit, and so on for all remaining bits of the number. For example:

BitOperationsEx.Reverse((byte)0b10100001) = 0b10000101

Hardware Acceleration

Gapothenko.FX.Numerics automatically employs hardware acceleration on conforming CPUs and architectures. If hardware acceleration is not available for a particular operation then a highly-optimized software fallback implementation is used instead.
