Glenn has a need to return the three least significant digits of a four-digit number and is wondering how this can best be done. As with many tasks in Excel, there are a number of ways you can derive the desired information. One way is to use the MOD function, in this manner:
This function divides the value in cell A1 by 1000 and then returns what is left over. Provided that the value in A1 is a four-digit integer, then you'll get the result you desire.
Another similar method of determining the desired values is to use a function that is normally used with text values:
This returns the three right-most characters (digits) of whatever is in cell A1. If you think that it is possible that A1 could have some non-digit characters in it, then you should wrap the function in the VALUE function, like this:
Of course, it is very possible that any of the approaches discussed so far will give undesired results. While they work well if the value in A1 is an integer value, they don't work that well if the value is a real number, such as 12.36 or 105.2, having four significant digits. In these cases you may want to use a formula such as the following:
