I would like to remove all rounding from my SEP file. I have tried altering/removing several variables, however my begin/end of SE transition is always rounded to the nearest whole number. Thank you
Here is the body of the SEP file I am using:

Try setting all of the *Rounding* values (e.g., eRoundingIncrement, runoffLengthRoundingIncrement, totalLengthRoundingIncrement , etc.) to zero.
This document provides a lot of help in setting up sep files: Guide: Setting Up Superelevation SEP Files.

Thank you for your help, that fixed it. I was thinking that "stationRoundingIncrementMethod = DISTRIBUTION_NO_ROUNDING" would handle the rounding issue, but apparently you need to change all of the numbers as well. I didn't change "eRoundingIncrement" though, since is not related to length.
