Rounding rules

1. Find the place you’re rounding to (hundredths = 2nd digit after the point).
2. Look at the next digit. 5 or more: round up. 4 or less: keep the digit.
3. Drop the remaining digits.

3.14159 to the nearest hundredth is 3.14; 2.675 is 2.68. Banker’s rounding sends exact halves to the even digit (2.5 → 2, 3.5 → 4) to avoid bias when summing many rounded values. Negative numbers round half away from zero here (−2.5 → −3).
