Hi David, I am trying to sort out two other issues with the Windows binaries, but I can push out a new Windows installer tomorrow morning for you with this fix. We can talk offline if you want to talk about getting up and running with CMake, too.

However, I need to wait for the new NREL-binaries to use the fixed version (or maybe finally step into the CMake thing to get the Windows bins compiled by myself... ;-) ). Cheers, David 2012/4/30 Gregory J. Ward <gregoryjw...@gmail.com<mailto:gregoryjw...@gmail.com>> Hi David, I found the problem, and can figure out how to fix it. The code assumes that exponents have two digits only, which is still true on most Unix machines. I guess they're making room for "long double's" (128-bit IEEE float) and don't have different code for that than the "regular" doubles. I will check in a fix later today -- thanks so much for spotting this.
