## Floating Point BCMath Support
By default, `MathExecutor` uses PHP floating point math, but if you need a fixed precision, call **useBCMath()**. Precision defaults to 2 decimal points, or pass the required number.
`WARNING`: Functions may return a PHP floating point number. By doing the basic math functions on the results, you will get back a fixed number of decimal points. Use a plus sign in from of any stand alone function to return the proper number of decimal places.

## Division By Zero Support:
Division by zero throws a `\NXP\Exception\DivisionByZeroException` by default
