A Note About "Rounding"

In Excel, numbers can "round" in two ways.

First, they can round up or down. With this type of rounding, numbers get larger when they are rounded up, and smaller when they are rounded down.

Second, numbers can round towards zero or away from zero. When positive numbers are rounded towards zero, they get smaller; when negative numbers are rounded towards zero, they get larger.

Although Microsoft uses "round up" and "round down" to describe both types of rounding, we use "round up" or "round down" to describe the first type of rounding. And we use "round towards zero" or "round away from zero" to describe the second type.


You can download this example workbook here, along with all other example workbooks I've completed for this Excel help area.

CEILING.PRECISE  rounds both positive and negative numbers up. A Significance value of 1 rounds the number up to the nearest integer.

The sign of the Significance value doesn't matter, because CEILING.PRECISE uses the absolute value of the Significance value.

To illustrate how CEILING.PRECISE works, the "b" examples show how using INT can produce the same results as the "a" examples.
