I guess the -g option for g.region will give me decimal values. Unlike the way I was handling it before, however, it's format requires me to parse the region file a little differently than a standard region file. If you know of a way to do this without having to parse the "n=23.7223" to pull out the decimal value, I'd be interested in hearing about it. Otherwise, I guess that's what I'm going to have to do. It might work out for the best anyway.
