The ncccomma package amends the behaviour of the comma in formulae so that it will behave as a decimal separator if followed by a decimal digit, but as punctuation otherwise. (The set of characters that determine its behaviour is configurable, but the set of decimal digits is the default.)

The package is part of the ncctools bundle.
