About Add Commas to Integers
A thousands separator splits a long number into groups of three digits counted from the right, so 1234567 becomes 1,234,567. This tool finds every run of four or more digits in your text and inserts the chosen separator; the rest of the text is left unchanged. It is meant for whole numbers: a run of four or more digits after a decimal point is grouped as well.
