This page opens the rounding calculator with the hundreds place preset, turning any figure into the nearest multiple of 100 and explaining which digit settled it.
Only the tens digit votes. 449 rounds down to 400 because the tens digit is 4 — the tempting chain 449 → 450 → 500 is a well-known mistake, since rounding may only happen once, off one digit. 1,250 is a perfect tie: half up sends it to 1,300, banker's half even sends it to 1,200 because the hundreds digit 2 is already even. Floor and ceiling ignore the digit entirely and always go down or always go up.
Hundreds are the natural resolution for estimating event attendance, rounding salaries in job ads, or quoting distances and prices where the fine detail is noise. The calculator does the digit work exactly and locally — nothing you type leaves the page.
