Strange math behaviour... could someone explain this ?

Thank you so much for your explanations. As for rev users, I strongly
suggest that this "potential problem" should be mentioned in the doc,
at least in the part dedicated to the trunc() function...

Nevertheless, how do you explain that the following :

  put 36 into A
  put 34.2 into B
  put A-B into C

  put C*100 into C
  put trunc(C)

returns 180 with Rev 2.5 on Mac OS9, but returns 179 on other
platforms such as Linux or Win2000 ?

Just curious...
