To cast (C style) you must put the type that you are going to in parenthesis.
I.e. From double to int:
double d = 5.0;
int i = (int)d;
I looked in a couple of books of mine to make sure I'm right, and I did see some
examples of something like int(d); but I've never been successful with that
method. Hopefully, soon egcs will support the ANSI Standard C++ methods of
typecasting:
e.g. Again, from int to float:
double d = 5.0;
int i = static_cast<int>d;
Anyone else?
