Good to know
A number exactly halfway is rounded to the even neighbour ("banker's rounding"), not always up: 2.5 โ 2, 3.5 โ 4, 1.25 โ 1.2. If you need halves of positive numbers to always go up, add a tiny amount (for example 0.0000001) with Add before rounding.
- Some decimals cannot be stored exactly, so a value that looks like a half may be slightly below it:
1.005to 2 digits gives1, not1.01. - Result has no trailing zeros:
7with 2 digits stays7, not7.00. To show7.00, format the number as text when you display it.
