Formula:

To round a number to the nearest hundred, you primarily look at the tens digit:

  • If the tens digit is 0, 1, 2, 3, or 4 (i.e., the number ends in 00-49), you round down to the previous hundred. For example, 349 rounds to 300.
  • If the tens digit is 5, 6, 7, 8, or 9 (i.e., the number ends in 50-99), you round up to the next hundred. For example, 350 rounds to 400.

The calculation performed by this tool is simply: Rounded Value = ROUND(Number / 100) * 100
