Ignore last N digits after the decimal point

That worked splendidly. Thanks!

Hello,

For BC3 Standard, the easiest method would be to define a Regular Expression that matches on the Important part of the number, and then everything else is unimportant. Would this work for your comparison?
\d+\.\d{3}

For BC3 Pro, you can create a Text Replacement in the Session Settings, Replacements tab. Here, create:
(\d+\.\d{3})\d*
RegEx that replaced with:
$1

This Replacement does not require you to define 'Everything Else' as unimportant, but you may need to create two replacements: one for Left to Right and one for Right to Left.

Please let us know if you have any questions.

What regex would I use if I wanted to ignore the last n digits after a decimal point?

X1342.123543 and X1342.123 should match.
