/**
* Compares this BigDecimal with the specified BigDecimal.

* Two BigDecimal objects that are equal in value but have a different scale (like 2.0 and 2.00)
* are considered equal by this method. This method is provided in preference to individual
* methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=).
* The suggested idiom for performing these comparisons is: (x.compareTo(y) <op> 0),
* where <op> is one of the six comparison operators.
*
* @param Number|float|int|string $that
*
* @return int - -1, 0, or 1 as this BigDecimal is numerically less than, equal to, or greater than val.
*
* @throws \DivisionByZeroError
