angleToSignedFraction Method

Return the fractionalized position of the given angle with respect to this sweep.

  • The start angle returns fraction 0
  • The end angle returns fraction 1
  • Interior angles (and their multiples of 2PI) return fractions in [0,1].
  • Exterior angles return fractions outside [0,1] according to toNegativeFraction.

angleToSignedFraction(theta: Angle, toNegativeFraction: booleanfalse, zeroSweepDefault: number0.0): number

@returns fraction, or zeroSweepDefault if this sweep is empty

Parameter Type Description
theta Angle input angle
toNegativeFraction boolean convert an exterior angle to a negative number (true), or to
a number greater than one (false, default). If false, this is just angleToPositivePeriodicFraction.
zeroSweepDefault number return value when this sweep is empty (default 0).

Returns - number

fraction, or zeroSweepDefault if this sweep is empty
