Hello Michael,
        thank you for your bug report.

Actually, wn == 1.5, not 1.  Awk does all computation in double, so

      pn = 0; qn = 3
      wn = (pn + qn) / 2

is not what you want.  The following would be better:

      wn = int((pn + qn) / 2)

Unfortunately, awk is not so close to C as you seem to suppose.

When you printf %d, the number is converted to int, ie. truncated.
The following commands would reveal the true value of wn, though:
        print wn
        printf("%s\n, wn)

Each of these commands forces conversion to string, not to integer, which
doesn't hide the fraction part.

Hope this helps,
