[Equest-users] Temperature in weather data

This is not possible at present without changing the DOE-2.2 source code 
to read a weather input file with decimal values.
When DOE-2 was first designed in the early 1980's, memory was a big 
concern, so the weather data was reduced to integers and then packed, 
which is why the DOE-2 *.BIN file is so small (146K). I have actually 
developed a modified file format for *.BIN where I save an extra digit 
of precision, i.e., temperatures to 0.1F instead of 1 F, but the source 
code would also need to be changed slightly to read this extra 
information. I've mentioned this to the developer of eQUEST/DOE-2.2 and 
will be experimenting with
making this change to the source code. If and when it's proven to work 
and gets incorporated into DOE-2.2, I'll let everyone know. I welcome 
anyone who thinks this is a useful modification to send me an e-mail. It 
might spur me on to do something!
