When the Round off depreciation parameter is set to 1.00, the system creates an additional depreciation period where the remaining cents between 0.01 to 0.49 to be depreciated.

The idea here is the following:

Within the book setup, when the user inserts in the Round off depreciation's field a value different than 0.00, a tick box to appear next to or under the parameter saying "Fully depreciation on last depreciation period".

When that tick box is being ticked, the Round off depreciation rule (set by the user) not to apply for the last payment and the whole remaining NBV amount to get generated in the last period proposal, instead of creating an additional period where the cents to get depreciated.
