Rounding Calculator

What is a Rounding Calculator?

A Rounding Calculator is a tool that rounds numbers to a specified place value, such as the nearest whole number, tenth, hundredth, or thousandth. It simplifies numbers while maintaining their approximate value.

Common rounding types include:

• Round to the nearest whole number: 4.7 → 5, 6.3 → 6
• Round to the nearest tenth: 3.67 → 3.7
• Round to the nearest hundredth: 2.345 → 2.35
• Round to the nearest thousandth: 5.67892 → 5.679

Rounding follows the "5 or more, round up; less than 5, round down" rule.
