Really?

When I'm setting a budget, it's going to be in dollars. If I'm getting prices in cents, I have to remember to convert, or I'm going to make the same mistake your parent comment did.

The currency is dollars, not cents. Most prices are set in dollars, not cents. Most transactions are performed in dollars, not cents. Budgeting is done in dollars, not cents.

Save trouble and use the same units everybody else does.
