* Rational approximation to a floating point number with bounded denominator using Mediant Method.
* For example, 333/1000 will become [0, 1, 3] (1/3), 1414/1000 will be [1, 2, 5] (1 2/5).
* Uses algorithm from this npm package - https://www.npmjs.com/package/frac
* Can be seen here https://github.com/SheetJS/frac/blob/d07f3c99c7dc059fb47d391bcb3da80f4956608e/frac.js
* @receiver - number that needs to be approximated
* @param d - maximum denominator (i.e. if 10 then 17/20 will be 4/5, if 20 then 17/20).
* @param mixed - if true returns a mixed fraction otherwise improper (i.e. "7/5" or "1 2/5")
