How to round numbers
Rounding replaces a number with a nearby, simpler value at a chosen place value. Find the digit right after the place you are rounding to: 5 or greater rounds the value up, otherwise it stays. Rounding makes numbers easier to read and estimate with while keeping them close to the original.

Frequently asked questions
How does rounding work?
To round to a given place, look at the digit just after it. If that digit is 5 or more, round up; if it is 4 or less, round down. This calculator uses standard round-half-up.
How do I round to the nearest ten or hundred?
Choose 10, 100, or 1000 as the "round to nearest" value. For example, 1234 rounded to the nearest hundred is 1200, and 1250 rounds to 1300.
Can I round to decimal places?
Yes. Set the "round to nearest" value to 0.1 for one decimal place, 0.01 for two, and so on.
