radiansToPositivePeriodicFractionStartEnd MethodStatic

Return the fractionalized position of the given angle (as radians), computed with consideration of 2PI period.

  • consider radians0 as start angle of the sweep and radians1 as end angle of the sweep
  • the start angle is at fraction 0
  • the end angle is at fraction 1
  • interior angles are between 0 and 1
  • all exterior angles are at fractions greater than 1
  • allows period shift

radiansToPositivePeriodicFractionStartEnd(radians: number, radians0: number, radians1: number, zeroSweepDefault: number0.0): number

@returns nonnegative fraction, or zeroSweepDefault if the sweep is empty.

Parameter Type Description
radians number input angle (in radians)
radians0 number start angle of sweep (in radians)
radians1 number end angle of sweep (in radians)
zeroSweepDefault number return value when the sweep is empty (default 0)

Returns - number

nonnegative fraction, or zeroSweepDefault if the sweep is empty.
