Method Detail

clamp

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

Clamps a double value to a given range.

Parameters:

x - the value to clamp

min - the minimum value of the range

max - the maximum value of the range

Returns:

the clamped value

clamp

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

Clamps an int value to a given range.

Parameters:

x - the value to clamp

min - the minimum value of the range

max - the maximum value of the range

Returns:

the clamped value

log10

public static double log10(double x)

Computes the base-10 logarithm of a double value.

• If the argument is NaN or less than zero, then the result is NaN.
• If the argument is positive infinity, then the result is positive infinity.
• If the argument is positive zero or negative zero, then the result is negative infinity.

Parameters:

x - a positive number

Returns:

the value log a, the base-10 logarithm of the input value
