 		 #96019 - Wrong again!
Responding to: ???'s previous message
I said:
The original post used only integers...

Donald Catto said:
The original post was:
Save This Code
#define Xtal 22.1184
#define tic12 (12/Xtal)
#define _10msec (65536 - ((1000 * 10) / tic12))
which does have a floating point constant in it.

Oh yes - so it does.

I'm wrong again... :-(

But I agree with Michael: it'd be far better not to use floating-point for the crystal frequency - the integer number of Hz would be fine.
