Forgive me if I sound naive...

How do I get c to recognize a function as returning a float and not
a double?  It seems the moment I declare something as a function, the
compiler cast it as double.  I am primarily using sizeof to determine
the type.

Here is a sample code.

float f1()
{  return( (float) 10.0);
}

main()
{  float f1(), res;
   res = f1();
   printf("sizeof f1() is %d\n",sizeof(f1()));
   printf("sizeof res is %d\n",sizeof(res));
}

This program invariable returns 8 and 4, not 4 and 4.   Help.
