angleToSignedPeriodicFraction Method

Return the fractionalized position of the given angle (as Angle) computed with consideration of 2PI period and with consideration of angle sweep direction (CW or CCW).

  • the start angle is at fraction 0
  • the end angle is at fraction 1
  • interior angles are between 0 and 1
  • negative fraction for angles "before" the start angle
  • fraction larger than one for angles "after" the end angle
  • allows period shift

angleToSignedPeriodicFraction(theta: Angle, zeroSweepDefault: number0.0): number

@returns fraction, or zeroSweepDefault if this sweep is empty.

Parameter Type Description
theta Angle input angle
zeroSweepDefault number return value when this sweep is empty (default 0)

Returns - number
