The values in the "options" dictionary returned from the parser()
function are always strings. You can parse the string with:
myoption = map(float, options['myoption'].split(','))
The option definition in the script should have:
#% type: double
#% multiple: yes
This allows g.parser to validate the option syntax, so you can rely
upon the string being in the correct format. If the values have a
fixed range, you can use e.g.:
#% options: 0.0-1.0
to have the parser check that the values fall within the range.
