Dear Sir or Madam,
I am a student from the German university of hildesheim
(http://www.uni-hildesheim.de) and I am trying to find out how the gcc
compiler handles implicit casting.
For more a better understanding, I would like to know the rules that are
applied when handling something like this:
double d = 1.4;
float fa = 0.4f;
float fb = 0.4f;
int i = d + fa + fb; // ignoring the warnings
Is there any documentation available that covers this issue? Or can one
generally say that gcc will do the casting as late as possible?
Thank you in advance,
Curt Nowak

Hi Curt,
I believe that GCC will do it this way...
int i = (int)((d + (double)fa) + (double)fb);
...which is the way that C/C++ does it.
HTH,
