1st project Do functions need to return a value (all 4)

10:52pm Tue 10th Sep, ANONYMOUS

If they don't have a return value, is their default return value 0.0, or should it be a void function instead?

I think either is fine, but returning 0.0 is probably easier.

Hi, currently I have all the functions double in the translated c file and it works fine even if the function doesn't have a return statement. I read that the return value is undefined for such functions in c so I just wanted to confirm that the return value of a function with no return statement won't be used in an expression in the ml file or do I need to check for that and throw an error in such a case?

Just add return 0.0 to the end of your functions if they don't have a return statement.
