Public Static Functions

static double mod_2pi(double val)

Transform from \( [-\inf, \inf) \) to \( [0, 2\pi) \) applying \(2\pi\) modulus.

Returns:

value modulus in the range of \( [0, 2\pi) \)

static double mod(double a, double b)
static double getAngContinuity(double prev_val, double val)

Parameters:
  • a – first angle

  • b – second angle

Returns:

difference between both angles

static double getAngleAvg(double a, double b)

Get the angle that is between a and b in the shortest direction.
