[Gretl-devel] Default value specification for scalar and integer arguments

Hi, I want to ask whether the following (which is working!) is actually according to the hansl spec. Consider the session at the end of the message. Hansl allows to specify the default value [0] both for 'scalar' and 'int', without requiring minimum or maximum values. But the way I read the paragraph "Function parameters: optional refinements" in the user guide, this would seem to be actually a syntax error. Instead for non-bool types it should be [::0]. Or if gretl is actually treating this as an implicit bool, what are the consequences of that? None, i.e. can the function body still do arbitrary calculations with the passed scalar value? Also (and I feel like having deja-vus again) notice that in the check2() function an integer parameter is specified, but if the caller passes 0.5, there is no type error, instead the argument is converted to its integer component. I do not think this is obvious, is this documented somewhere? Thanks, sven ? function void check1 (scalar in[0]) ? function void check2 (int in[0]) ? check1() in = 0.00000000 ? check1(3) in = 3.0000000 ? check1(1) in = 1.0000000 ? check1(0.5) in = 0.50000000 ? check2() in = 0.00000000 ? check2(3) in = 3.0000000 ? check2(1) in = 1.0000000 ? check2(1.6) in = 1.00000000
