Hi Dirk,
I am just writing protocol files for a Lauda chiller unit (RE 304 and RE 306).
http://www.lauda.de/hosting/lauda/website_en.nsf/urlnames/kaeltethermostate_produkte
It requires floats as parameters in a special way:
Example "OUT SP 00 20.01"
The parameter here can range from 1 to 3 digits in front and 2 digits behind the
decimal point.
If I use %6.2f it will work for "120.01", but will write " 20.01" in case of the
value "20.01".
The extra blank will cause the unit to flag the command as error.
I can use the "-" modifier to get rid of the leading space...
But then the string sent looks like "20.01 " and the unit will again
complain. Can I suppress leading and trailing spaces?
Cheers, Burkhard
