# Numeric Formats, Masks

> [HTML Version](numericformatsmasks.htm)

Sample program TSTNUMFOR ([source online here](https://bitbucket.org/microsabio/exlib/src/master/908068/tstnumfor.bp?at=default&fileviewer=file-view-default#_blank)) illustrates the use of built-in numeric formats (NUMFMT\_xxx) and also custom masks. The raw value is shown in the first column, the format code or mask in the center, and the formatted value on the right.
