Class QQ

The QQ class represents a rational number, ℚ.

The QQ implementation is that of an immutable (value) type.

The numerator and denominator are reduced to their lowest form.

Construct new instances using the static valueOf method.

Accessors

denom

  • get denom(): number

  • The denominator of the rational number.

    Returns number

numer

  • get numer(): number

  • The numerator of the rational number.

    Returns number

Methods

add

  • add(rhs): QQ

  • Parameters

    Returns QQ

    this + rhs

div

  • div(rhs): QQ

  • Parameters

    Returns QQ

    this / rhs

equals

  • equals(other): boolean

  • Determines whether two rational numbers are equal.

    Parameters

    Returns boolean

    true if this rational number equals the other rational number.

hashCode

  • hashCode(): number

  • Returns number

    37 * numerator + 13 * denominator

inv

  • inv(): QQ

  • Computes the multiplicative inverse of this rational number.

    Returns QQ

    1 / this

isOne

  • isOne(): boolean

  • Returns boolean

    true if this rational number is one (1), otherwise false.

isZero

  • isZero(): boolean

  • Returns boolean

    true if this rational number is zero (0), otherwise false.

mul

  • mul(rhs): QQ

  • Parameters

    Returns QQ

    this * rhs

neg

  • neg(): QQ

  • Computes the additive inverse of this rational number.

    Returns QQ

    -this

sub

  • sub(rhs): QQ

  • Parameters

    Returns QQ

    this - rhs

toString

  • toString(radix?): string

  • Computes a non-normative string representation of this rational.

    Parameters

    • Optional radix: number

    Returns string

Static valueOf

  • valueOf(n, d): QQ

  • Parameters

    • n: number
    • d: number

    Returns QQ
