Hi, I'm really excited about weave - it's great fun ! Now I get this error message: Conversion Error:, received 'int' type instead of 'float' for variable 'pz' Apparently if I call my functions "f" like f(5) but f was defined in C as: void f(double pz) I get that error. Did I understand this correct ? And how could I specify a "converter" so that a int gets "automagically" converted into a float !? Thanks for weave, Sebastian Haase
