but if i omit $2, the float's value is 0 and not 1. how to test if a creation parameter was specified?
You test, if it's 0!
loadbang | [f $2] | [select 0] | | [default( | | / [s something]
Replace "default" with your default.
in this case, if i specify 0 as second argument, internally i get [default-value] instead of zero. inn other programming languages, you can test $2 against a null val, or you can check the argument count...
