Member Function Documentation

int Loyc.Math.IBinaryMath< T >.CountOnes

(

T

a

)

Returns the number of '1' bits in 'a'.

Implemented in Loyc.Math.MathFL32, Loyc.Math.MathFL16, Loyc.Math.MathF23, Loyc.Math.MathF16, Loyc.Math.MathF8, Loyc.Math.MathUL, Loyc.Math.MathL, Loyc.Math.MathU, Loyc.Math.MathI, Loyc.Math.MathU16, Loyc.Math.MathI16, Loyc.Math.MathU8, and Loyc.Math.MathI8.

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.)

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

T Loyc.Math.IBinaryMath< T >.Shr	(	T	a,
		int	amount
	)

Shifts 'a' right by the specified number of bits.
