Class Fraction

constructor

• new Fraction(
      numerator?: number,
      denominator?: number,
      wholeValue?: number,
      simplify?: boolean,
  ): Fraction

  Parameters

  • numerator: number = 0
  • denominator: number = 1
  • wholeValue: number = 0

    the integer number, needed for values greater than 1

  • simplify: boolean = true

    If simplify is true, then the fraction is simplified to make both the numerator and denominator coprime, and less than maximumAllowedNumber.

  Returns Fraction

Denominator

• get Denominator(): number

  Returns number

• set Denominator(value: number): void

  Parameters

  • value: number

  Returns void

Numerator

• get Numerator(): number

  Returns number

• set Numerator(value: number): void

  Parameters

  • value: number

  Returns void

RealValue

• get RealValue(): number

  Returns number

WholeValue

• get WholeValue(): number

  Returns number

• set WholeValue(value: number): void

  Parameters

  • value: number

  Returns void

Add

• Add(fraction: Fraction): Fraction

  Adds a Fraction to this Fraction. Attention: This changes the already existing Fraction, which might be referenced elsewhere! Use Fraction.plus() for creating a new Fraction object being the sum of two Fractions.

  Parameters

  • fraction: Fraction

    the Fraction to add.

  Returns Fraction

calculateNumberOfNeededDots

• calculateNumberOfNeededDots(): number

  Returns number

clone

• clone(): Fraction

  Returns Fraction

CompareTo

• CompareTo(obj: Fraction): number

  Parameters

  • obj: Fraction

  Returns number

distanceFromBeat

• distanceFromBeat(timeSignature: Fraction): number

  Parameters

  • timeSignature: Fraction

  Returns number

Equals

• Equals(obj: Fraction): boolean

  Parameters

  • obj: Fraction

  Returns boolean

expand

• expand(expansionValue: number): void

  Parameters

  • expansionValue: number

  Returns void

GetExpandedNumerator

• GetExpandedNumerator(): number

  Returns the unified numerator where the whole value will be expanded with the denominator and added to the existing numerator.

  Returns number

gt

• gt(frac: Fraction): boolean

  Parameters

  • frac: Fraction

  Returns boolean

gte

• gte(frac: Fraction): boolean

  Parameters

  • frac: Fraction

  Returns boolean

IsNegative

• IsNegative(): boolean

  Returns boolean

isOnBeat

• isOnBeat(timeSignature: Fraction): boolean

  Parameters

  • timeSignature: Fraction

  Returns boolean

lt

• lt(frac: Fraction): boolean

  Parameters

  • frac: Fraction

  Returns boolean

lte

• lte(frac: Fraction): boolean

  Parameters

  • frac: Fraction

  Returns boolean

Quantize

• Quantize(maxAllowedDenominator: number): Fraction

  Brute Force quanization by searching incremental with the numerator until the denominator is smaller/equal than the desired one.

  Parameters

  • maxAllowedDenominator: number

  Returns Fraction

Sub

• Sub(fraction: Fraction): Fraction

  Subtracts a Fraction from this Fraction. Attention: This changes the already existing Fraction, which might be referenced elsewhere! Use Fraction.minus() for creating a new Fraction object being the difference of two Fractions.

  Parameters
