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 )
