In some input fields, the values entered are rounded to 2 decimal digits. This makes it impossible to enter the exact amount needed.
For example, a salaried employee may have a weekly (or even yearly) amount in their contract rather than an hourly rate. It is not possible to enter the corresponding rate as these are always reduced to hourly rates, whether entered hourly, daily, or yearly.
This also applies to superannuation, where the super rate is truncated to 2 decimal digits, although more digits are entered.
I think that rounding should take place at the dollar payment point rather than at the rate or percentage entry.
