Re: [Chicken-users] Passing floats to and from foreign functions

Hi pluijzer ., You did not declare a prototype in test.scm (technically, test.c) for the functions in wrapper.c. I believe return values default to int if there is no prototype, and the float arg is promoted to double, but I'm not positive. Anyway, simply add the following to the top of
