Compiler (at least C compiler) Does not do typecasting. And if atof() returns
float, then printf("%f",atof(d)) will show it as float. Typecasting is done
on runtime by printf(), which does not know anything about atof().
And as I (and others) show before, his program works as expected
(shows float value).
