atof() takes a character pointer as its argument and returns a float, in C,
anytime you don't explicitly declare what a function returns, it is assumed
to be an integer (I know, I would prefer a warning also), that's what 
happened in this case, because you didn't #include <math.h> I got the same
result with my test program, but when you include the prototype for atof(),
it works perfectly. If you look up atof() in the Turbo-C reference guide, it
says "prototype in math.h,stdlib.h"
