Isn't there always a problem with tolerant comparisons to zero since tolerance is defined in terms of some small proportion of the number being compared? According to the Primer (system/extras/help/primer/tolerance.htm) "close enough is *relative *to the size of the numbers".
In the case of comparing to zero, you may need to resort to the standard old trick of comparing the absolute value of the number you expect to be zero to some small number, maybe the comparison tolerance itself: (9!:18'')>|1 o. 1p1 1 (9!:18'')>|1 o. (1p1)+1e_13 0 (9!:18'')>|1 o. (1p1)+1e_14 1 9!:18 '' 5.6843419e_14 On 12/1/06, Dan Bron <[EMAIL PROTECTED]> wrote:
