The strange bug happens because by the time you have made it to the penny calculation, the remainder is no longer a full two cents. If you display it with about 15 digits of precision, it is truly just a bit below, so the node returns almost a full penny as a remainder. This is largely due to the fact that floats cannot store base ten fractions precisely. The mixup rounds the value so that the small cumulative error resets. A different fixup would be to convert the initial value to units of pennies instead of dollars.
