!The above code does not work but with an error message :
!"floating point formats not linked"

Its a fact that the Turbo C linker doesn't link in the floating
point routines if it doesn't think they are needed.  So in some
circumstances you have to force them to be linked in by making
an appropriate reference.  I think just declaring a dummy function
call will work:   void dummy(float a);

(Its a bug if they want to fix it, a feature if they don't. :-)
