* floating subtraction to give exact remainders after the decimal, to be scaled into an integer.
* Extra trailing 0's are excluded. The output defaults to rounding to nearest, ties to even. You
* can enable rounding ties away from zero. Note: UNITY_DOUBLE param can typedef to float or double
* The old version required compiling in snprintf. For reference, with a similar format as now:
