Note to self...it's best to restart with a fresh session if you've been making modifications. everything appears to work fine without any of the above observed problems: >>> a=Number_with_uncert(3,1);y=a+cos(a);y.error 0.85888494187891229 >>> b=Number_with_uncert(4,1) >>> cos(a/b) <class '__main__.Semi_formal_expr_node'> object with result 0.731688868874 +- 0.213012112511 Sorry for the false alarm, /c -- http://mail.python.org/mailman/listinfo/python-list
