Given the following

--%<---
#%option
#% key: sea
#% key_desc: degrees
#% type: double
#% description: Aquisition's Sun Elevation Angle
#% options: 0.0 - 90.0
#% guisection: Metadata
#% required: yes
#%end
..
import grass.script as grass
..
def main()
     ..
     sea = options['sea']
     ..

if __name__ == "__main__":
     options, flags = grass.parser()
     sys.exit(main())
--->%--

Isn't supposed that sea is returned as a float? Is it really necessary to do

sea = float(options['sea'])

?

Grazie, Nikos

... this defines what type is *accepted* as input.

No, above is the definition for the accepted input type.

Yes.

Grazie Markus.

Is it too much work to make this automatic? I am trying to think why should a user/scripter want something else than the type that the parameter (in CLI or wx-GUI) requests?
