Is there a way to test is a number is zero, positive or negative? I tried this using the FP package as follows.<BR>
<BR>
\def\test#1{\FPifzero{#1} 0 \else \FPifpos{#1} 1 \else -1 \fi \fi}<BR>
<BR>
It works if the number is positive or negative but gives a Tex error about an extra \fi if the input is zero.<BR>
<BR>
Thanks.<BR><BR><br /><hr />Email Australia. <a href='http://emailaustralia.ninemsn.com.au' target='_new'>Be part of history. Take part in Australia's first e-mail archive with </a></body>
