Rounded Number:

A rounding calculator is a tool that helps you round numbers to a specified place value — like the nearest whole number, tenth, hundredth, or any other decimal or significant figure.

Why use a rounding calculator?

  • To simplify numbers for easier understanding or estimation.
  • When you don’t need exact precision but a quick approximation.
  • For financial calculations, measurements, or stats where exact decimal places aren’t necessary.

How does it work?

  1. You enter the number you want to round.
  2. You select the place value (like nearest whole number, tenth, hundred, etc.).
  3. It checks the digit right after your chosen place value to decide whether to round up or down.
  4. It gives you the rounded result.

When do you use it?

  • In math homework or exams when you need to round numbers.
  • In financial estimates, like rounding currency amounts.
  • In measurements where a rough estimate works fine (like distances or weights).
