Greetings! Would you be willing to test an axiom build with a fix for
this? Esp. comparing as many as possible bignum results like this
against your mathematica?

Take care,

axiom seems to have problems calculating sqrt(2). Using the following command

echo "digits(DIGITS); sqrt(2.)" | axiom

where DIGITS should be replaced by the numbers listed in the
corresponding column below. In the table below the last digits of the
output are shown in the second column. One can see that for DIGITS=121278-121280 the result is not correct. For 121290 digits the
result is OK again. As reference the output of Mathematica is given
in the last row.

Unfortunately I don't have time right now. I can do some tests once
the fixed version makes it into debian/testing.

Cheers, Heiko
