public static int clamp(int low,
int value,
int high)
Note: This method only produces sensible results if the lower bound is less than, or equal to, the higher bound.
low - Lower bound value.value - Value to clamp.high - Upper bound value.public static double exp(double x)
x - the power to raise e to.public static double log(double x)
x - a number greater than zero.public static int log2(int value)
The value zero and one both return zero.
value - The unsigned value to calculate log2 on.public static int log2(long value)
The value zero and one both return a log2 result of zero.
value - The unsigned value to calculate log2 on.
public static int wrap(int low,
int value,
int high)
Note: This method only produces sensible results if the lower bound is less than, or equal to, the higher bound.
low - Lower bound value.value - Value to wrap.high - Upper bound value.
