Round any number to 2 decimal places (nearest hundredth) instantly
• Look at the thousandths place (3rd decimal)
• If 5 or more, round up
• If less than 5, round down
• 3.14159 → 3.14 (1 < 5, round down)
• 2.3456 → 2.35 (5 ≥ 5, round up)
• 1.995 → 2.00 (5 ≥ 5, round up)
• 7.23 → 7.23 (already two decimals)

The hundredths place is the second digit after the decimal point. This is where we want to round to.
Example: In 3.14159, the hundredths digit is 4.
The thousandths place is the third digit after the decimal point. This determines rounding direction.
• If thousandths digit is 5, 6, 7, 8, or 9: Round up
• If thousandths digit is 0, 1, 2, 3, or 4: Round down
Example: In 3.14159, the thousandths digit is 1, so round down.
Adjust the hundredths digit based on the rounding rule, then remove all digits after it.
Example: 3.14159 becomes 3.14 (keep 14, remove 159)
The nearest hundredth is the second decimal place after the decimal point. It represents hundredths of a whole number (0.01, 0.02, 0.03, etc.). Rounding to the nearest hundredth means keeping only two digits after the decimal point.
Look at the thousandths digit (the third decimal place), which is 5. Since 5 rounds up, increase the hundredths digit from 4 to 5, giving you 3.15.
2.995 rounds to 3.00. The thousandths digit (5) means we round up, so the hundredths digit (9) becomes 10, which carries over, making the tenths digit 10 as well, resulting in 3.00.
Rounding to the nearest hundredth is common in financial calculations (cents), scientific measurements, test scores, and statistics. Two decimal places provide good precision while keeping numbers manageable.
Use the same rule: look at the thousandths digit. For example, -3.145 rounds to -3.15 (5 rounds the magnitude up), and -3.144 rounds to -3.14.
If the number has two or fewer decimal places, it stays the same (with trailing zeros if needed). For example, 3.14 stays 3.14, and 5.1 becomes 5.10.
