I use the simple and effective JSON package at www.squeaksource.com/JSON for my weather station stuff. Does the job nicely.

To keep my floating point number printing under control I use Printf package www.squeaksource.com/Printf and, for example, ‘%-0.1e’ printf: myFloat
The FormatString class comment describes it all reasonably neatly.
