time_fraction Function

private pure function time_fraction(self, k, k2, t) result(frac)

The fraction of the way in time from point k to point k2 (any two points: e.g. k + 1, or k - 1 with times running backward) at time t, kept within 0 to 1 (0 if their times are the same). No checks: k and k2 must be times.

Type Bound

Trajectory
