---|---|
System.Int32 | The population count of |
Remarks
This method is similar in behavior to the x86 instruction POPCNT
RotateLeft(Int32, Int32)
Rotates the current value left by the specified number of bits.
Declaration
public static int RotateLeft(this int value, int count)
Parameters
Type | Name | Description |
---|---|---|
System.Int32 | value | The value to rotate. |
System.Int32 | count | The number of bits by which to rotate. Any value outside the range [0..31] is treated as congruent mod 32. |
Returns
Type | Description |
---|---|
System.Int32 | The rotated value. |
RotateRight(Int32, Int32)
Rotates the current value right by the specified number of bits.
Declaration
public static int RotateRight(this int value, int count)
Parameters
Type | Name | Description |
---|---|---|
System.Int32 | value | The value to rotate. |
System.Int32 | count | The number of bits by which to rotate. Any value outside the range [0..31] is treated as congruent mod 32. |
Returns
Type | Description |
---|---|
System.Int32 | The rotated value. |
RoundUpToPowerOf2(Int32)
Rounds the current value up to a power of two.
Declaration
