Fraction Creation and Basic Operations.
Cracked a tough problem in making this Polarity Agnostic Decimal without a cheating "abs * sign of input".

it's quite fast, however still test for errors before production use.

  • Int Array (LOC 0/1)..
  • To/From Decimal(float)
  • Comparison ( < / == / >)
  • Add / Sub / Mult / Div
  • Invert polarity +/-
  • String output with 2 formats ..

make(_numerator, _denominator, _val)
  Parameters:
    _numerator: (int) above the line integer ie: ____ of (___ / bottom )
    _denominator: (int) below the line integer ie: ____ of (top / ______ )
    _val: (int) OPTIONAL (for no real reason including it) integer to multiply
  Returns: array<int> where index 0 is Numerator, 1 is Denominator

add(_fraction, _fraction2)
  Perform add operation (left adds right onto )
  Parameters:

  Returns: array<int> where index 0 is Numerator, 1 is Denominator

negative(_fraction)
  Perform Negative number inversion ie: (-1/2 => 1/2) or (3/5 => -3/5)
  Parameters:
    _fraction: (array<int>) Fraction Object to invert to/from negative
  Returns: array<int> where index 0 is Numerator, 1 is Denominator

isSmaller(_fraction, _fraction2)
  Check if first fraction is smaller
  Parameters:
    _fraction: (array<int>) left side Fraction Object
    _fraction2: (array<int>) right side Fraction Object
  Returns: True if smaller, false if bigger

isLarger(_fraction, _fraction2)
  Check if first fraction is larger
  Parameters:
    _fraction: (array<int>) left side Fraction Object
    _fraction2: (array<int>) right side Fraction Object
  Returns: True if smaller, false if bigger

isEqual(_fraction, _fraction2)
  Check if first fraction is equal
  Parameters:
    _fraction: (array<int>) left side Fraction Object
    _fraction2: (array<int>) right side Fraction Object
  Returns: True if smaller, false if bigger

fromDec(_input, _epsilon, _iterations)
  Convert Decimal to Fraction array
  note : this is my own Negative Number Capable (tiny speed loss)
  adaptation of the fastest algo out there
  Exclusive for Tradingview.

  Parameters:

    _iterations: (int) (OPTIONAL) Maximum iterations Till give up
  Returns: array<int> where index 0 is Numerator, 1 is Denominator

toDec()
  Convert Fraction to Decimal Output
  Returns: Float of fration

toString(_fraction)
  Create "A/B" or "A and B/C" String Value of Fraction.
  Parameters:
    _fraction: (array<int>) Fraction Object to invert to/from negative
  Returns: String as (-)? A and B/C format
