Methods
| CountBitsCleared(UInt32) | Counts the number of bits that are not set |
| CountBitsCleared(UInt64) | Counts the number of bits that are not set |
| CountBitsSet(UInt32) | Counts the number of bits that are set |
| CountBitsSet(UInt64) | Counts the number of bits that are set |
| CountLeadingOnes(UInt32) | Counts the number of consecutive 1's starting from the highest bit working down. |
| CountLeadingOnes(UInt64) | Counts the number of consecutive 1's starting from the highest bit working down. |
| CountLeadingZeros(UInt32) | Counts the number of consecutive 0's starting from the highest bit working down. |
| CountLeadingZeros(UInt64) | Counts the number of consecutive 0's starting from the highest bit working down. |
| CountTrailingOnes(UInt32) | Counts the number of consecutive 1's starting from the lowest bit working up. |
| CountTrailingOnes(UInt64) | Counts the number of consecutive 1's starting from the lowest bit working up. |
| CountTrailingZeros(UInt32) | Counts the number of consecutive 0's starting from the lowest bit working up. |
| CountTrailingZeros(UInt64) | Counts the number of consecutive 0's starting from the lowest bit working up. |
| CreateBitMask | Creates a bit mask for a number with the given number of bits. |
| GetClearedBitPositions(UInt32) | Returns the bit position for every bit that is cleared in the provided value. Bit positions are defined as 0-31; |
| GetClearedBitPositions(UInt64) | Returns the bit position for every bit that is cleared in the provided value. Bit positions are defined as 0-63; |
| GetSetBitPositions(UInt32) | Returns the bit position for every bit that is set in the provided value. Bit positions are defined as 0-31; |
| GetSetBitPositions(UInt64) | Returns the bit position for every bit that is set in the provided value. Bit positions are defined as 0-63; |
| IsPowerOfTwo(Int32) | Determines if the number is a power of 2. |
| IsPowerOfTwo(Int64) | Determines if the number is a power of 2. |
| IsPowerOfTwo(UInt32) | Determines if the number is a power of 2. |
| IsPowerOfTwo(UInt64) | Determines if the number is a power of 2. |
| RoundDownToNearestPowerOfTwo(UInt32) | Rounds a number down to the nearest power of 2. If the value is a power of two, the same value is returned. If value is zero, 1 is returned. |
| RoundDownToNearestPowerOfTwo(UInt64) | Rounds a number down to the nearest power of 2. If the value is a power of two, the same value is returned. If value is zero, one is returned. |
| RoundUpToNearestPowerOfTwo(UInt32) | Rounds a number up to the nearest power of 2. If the value is a power of two, the same value is returned. If the value is larger than the largest power of 2. It is rounded down. |
| RoundUpToNearestPowerOfTwo(UInt64) | Rounds a number up to the nearest power of 2. If the value is a power of two, the same value is returned. If the value is larger than the largest power of 2. It is rounded down. |
