I am a newbie in WeBWork from Puerto Rico. I installed it (http://webwork.uprm.edu) in a CentOS server using ww_install python script (https://github.com/aubreyja/ww_install), it is running so well.
Thank you very much to all who have contributed and contributes in this powerful tool.
I am coding some problems, I want restrict scientific notation like 3.25E3 in students solution. Of course, the problem is convert from scientific notation to standard.
I include the full code, it is in spanish, I hope this is not a problem. Maybe I'm not quite right encoding, suggestions are welcome.

I read from another post that this is useful,
