    If the number is of the format n.00..., returns n.
    If the decimal portion of the number has a repeating decimal, followed by up to two trailing
    numbers, such as:
  
    0.3333333
  
    or
  
    0.343434346
  
    It will return just one instance of the repeating decimals:
  
    0.3
  
    or
  
    0.34
