Various Methods of Rounding Numbers
Rounding numbers is a common task, and Excel provides quite a few functions that round values
in various ways.
You must understand the difference between rounding a value and formatting a value. When you
format a number to display a specific number of decimal places, formulas that refer to that
number use the actual value, which might differ from the displayed value. When you round a number,
formulas that refer to that value use the rounded number.
Table 111-1 summarizes the Excel rounding functions.
