Hello,

How do I format floating point values, either double or float? I want
to specify things like the precision during the formatting, i.e. how
many digits to include in the fractional digits, and so forth.

Currently, I am using this, for instance:

General: "%1$g"
Fixed: "%1$f"
Scientific: "%1$e" or "%1$E" (depending on whether lower or upper
case, respectively)

Thanks!

Best regards,

Michael Powell
