set num to num * 100 * theMultiplier -- multiplying and dividing by 100 before and after applying the multiplier helps avoid poor rounding results for some numbers due to inevitable loss of precision in floating-point math (e.g. `324.21 * 100 div 1 / 100` returns 324.2 but needs to be 324.21), though this hasn't been tested on all possible values for obvious reasons -- TO DO: shouldn't /10 be done after rounding is applied (in which case following calculations should use mod 10, etc)?
