Hey,
I've got an easy question for you for a change! When you typecast doubles to ints, does the compiler truncate the value or round the value? If I remember correctly this is compiler specific.
Example:
...
double num1=10.5;
int num2=(int)num1;
...
Does num2 become 10 or 11? Let me know,
James

You think that's an easy question? <grin>
I believe genmath floor()s the number so truncation.
The other maths libraries (ZX,cpc,z88) call the appropriate maths routine
in the ROM, I'm guessing that they also truncate.
cheers,
