Public methods

addExact

public static int addExact(int x, int y)

See addExact.

addExact

public static long addExact(long x, long y)

See addExact.

clamp

public static float clamp(float value, float min, float max)

This method takes a numerical value and ensures it fits in a given numerical range. If the number is smaller than the minimum required by the range, then the minimum of the range will be returned. If the number is higher than the maximum allowed by the range then the maximum of the range will be returned.

Parameters
`float value`	the value to be clamped.
`float min`	minimum resulting value.
`float max`	maximum resulting value.

Returns
`float`	the clamped value.

clamp

public static double clamp(double value, double min, double max)

Parameters
`double value`	the value to be clamped.
`double min`	minimum resulting value.
`double max`	maximum resulting value.

Returns
`double`	the clamped value.

clamp

public static int clamp(int value, int min, int max)

Parameters
`int value`	the value to be clamped.
`int min`	minimum resulting value.
`int max`	maximum resulting value.

Returns
`int`	the clamped value.

clamp

public static long clamp(long value, long min, long max)

Parameters
`long value`	the value to be clamped.
`long min`	minimum resulting value.
`long max`	maximum resulting value.

Returns
`long`	the clamped value.
