Method Details

interpolate

public static double interpolate(double a,
 double b,
 double progress)

Interpolates between two values based on the given progress.

Parameters:

a - the start value

b - the end value

progress - the interpolation progress (0.0 to 1.0)

Returns:

the interpolated value

square

public static double square(double value)

Squares the given value.

Parameters:

value - the value to be squared

Returns:

the squared value

sqrt

@Deprecated
public static double sqrt(double input)

Deprecated.

Call Math.sqrt(double) directly. This now simply delegates to it; the former bit-hack approximation was less precise than the JDK intrinsic (and wrong at 0) without being faster.

Computes the square root of the given value.

Parameters:

input - the value to compute the square root of

Returns:

the square root of input
