Where did the paise go?
Short answer. The int cast cut off the decimal part, so 99.99 became 99.
Does casting round to 100?
No. It cuts toward zero.
Remember
| Big to small: write a cast |
| Decimals are cut, not rounded |
Ninety nine point nine nine became ninety nine. Why? Double to int needs a cast. The cast cuts off the decimal. It never rounds. Big to small needs a cast. Decimals are cut, not rounded.
