Budget Bandit stores every amount as a whole number internally, not as a decimal. This is a precision choice, and it is the reason the math always adds up to the cent. You never have to think about it — you see and type dollars everywhere.

Why whole numbers

Computers are bad at decimals. Store 0.10asadecimalandaddittentimesandyoucandriftto0.10 as a decimal and add it ten times and you can drift to 0.9999999 instead of $1.00. Across a budget with thousands of transactions, those rounding errors pile up and balances stop matching. The fix is to store money as an integer count of a tiny unit, then divide for display. Budget Bandit keeps four digits of precision under the hood, so $1.00 is stored as a round whole number and every sum stays exact. Reconciling an account to the cent works because there is no hidden fraction to chase.

You always work in dollars

This is purely an internal detail. Everywhere you look or type, the app is in dollars:
  • You enter 45.99 and the app records $45.99.
  • You read $1,240.00 Available, not a count of internal units.
  • Reports, totals, and exports are all in dollars and cents.
You will never be asked to enter or read an internal unit. If a number ever looks off by a rounding error, that is a bug worth reporting — the storage model exists precisely to prevent it.
