It took me awhile to write the function def for f2c, but that was mostly b/c I didn't quite understand how to use the "round" function. I also came across a few errors that I had no explanation for, but I found that they were mostly syntax errors. Hopefully, overtime I will become more accustomed to spotting syntax errors and eventually be able avoid then entirely.
