Number of Decimal places.

By default the decimal places set to 2 digit.
But if you need more than that, Deskera provide up to 4 decimal places.
You can changes this setting in Setting > Organisation Profile > Finance tab > No. Of Decimal Places field.

Pls note, once we have set the decimal places up, i.e. set to 3 decimal places, we will not be able to change back to 2.
