What if you were trying to rigid tap with FeatureCAM but can't make it work because the feed rate is only displaying 1 decimal place?  Open the "post options" window either from the "Manufacturing" menu or you can just click on the name of the postprocessor in the "status bar" (lower right hand corner) then select the "edit button". Now select "cnc info", "words1" and you will notice that in the "format" column for feed the value will be 3.1 which means 3 places to the left of the decimal and 1 to the right. If you change it to 3.3 it will output 3 decimal places after the 0 and 3.4 would output 4 places to the right of the decimal.
