To insert amount more than 3 decimal places in deduction

Hi, I am having problem to make a deduction in three decimal place. In, it only auto generated to two decimal place. How do we set the amount in three decimal places. Beacuse it effecting the final salary amount in payslips, which is different from what I calculated in excel salary calculation.

May I know which country do you come from and why do you need to show 3 decimal places?

I am from Malaysia, and i need to show 3 decimal place to ease me to calculate final salary after deduction

I see. Sorry that I do not have plans to support such use case, as there is presently no way to pay up to 3 decimal place in Malaysia yet.
