I'm trying to get a program to tell me the version of a dll file and the version of some hardware I'm using. Both should be chars, but that datatype isn't available in apwin basic. The only data type that allows me to run the program is a double, but the output I get is something like 1.59(few more numbers here)E-317. Not sure how to handle this exponential. Tried converting to different datatypes, nothing worked for me so far.

I'm expecting both versions to be "2.1" ...any tips on how to convert that exponential to get the 2.1?
