SUMMARY

In Microsoft Excel, if you want to truncate a number in a Microsoft Visual Basic for Applications macro or procedure, you can use the Int() function or the Fix() function to remove the fractional part of the number and return the resulting integer value.

However, if you want to pass an argument to specify a certain number of decimal places that you want to remain, as you can with the Microsoft Excel version 4.0 TRUNC() function, which has a num_digits argument, you must create a custom function. An example of such a function is in the "More Information" section of this article.
