There is absolutely no need for multiple filterscripts, use callback hooking and compile them into the gamemode but to answer your question try this.

#include <a_samp>

pawn Code:

main() {
    new Float:t = Test();
    printf("%f", t);
}

forward Float:Test();
public Float:Test() { return 1.0; }

You can test that code on this website.
