Member Function Documentation
◆ CountOnes()
| int Loyc.Math.IBinaryMath< T >.CountOnes | ( | T | a | ) |
Returns the number of '1' bits in 'a'.
◆ Log2Floor()
| int Loyc.Math.IBinaryMath< T >.Log2Floor | ( | T | a | ) |
Returns the floor of the base-2 logarithm of x. e.g. 1024 -> 10, 1000 -> 9
The return value is int.MinValue for an input of zero (for which the logarithm is technically undefined.)
◆ Shl()
| T Loyc.Math.IBinaryMath< T >.Shl | ( | T | a, |
| int | amount | ||
| ) |
Shifts 'a' left by the specified number of bits.
A shift amount A negative shift amount produces undefined results
◆ Shr()
| T Loyc.Math.IBinaryMath< T >.Shr | ( | T | a, |
| int | amount | ||
| ) |
Shifts 'a' right by the specified number of bits.
