Method Detail

normalize

public static double normalize(double angle,
                               double center)

Normalize an angle in an interval of size 2π around a center value.

Parameters:

angle - Value to be normalized.

center - Center of the desired interval for the result.

Returns:

a - 2 * k with integer k such that center - pi <= a - 2 * k * pi <= center + pi.

normalizeBetweenMinusPiAndPi

public static double normalizeBetweenMinusPiAndPi(double angle)

Normalize an angle between -π and π.

Parameters:

angle - Value to be normalized.

Returns:

a - 2 * k with integer k such that -pi <= a - 2 * k * pi <= pi.

normalizeBetweenZeroAndTwoPi

public static double normalizeBetweenZeroAndTwoPi(double angle)

Normalize an angle between 0 and 2π.

Parameters:

angle - Value to be normalized.

Returns:

a - 2 * k with integer k such that 0 <= a - 2 * k * pi <= 2 * pi.
