failed nchoosek test in mercurial tip

[Thorsten Meyer]

Hi,

while doing
	make check
with the latest mercurial tip on an intel pc running debian, I got this test failure:

>>>>> processing /home/thorsten/hg/octave/scripts/specfun/nchoosek.m
  ***** assert (nchoosek(100,45), bincoeff(100,45))
!!!!! test failed
assert (nchoosek (100, 45),bincoeff (100, 45)) expected
 6.1448e+28
but got
 6.1448e+28
values do not match

Trying directly in octave, I get:
octave:2> (nchoosek (100, 45)-bincoeff (100, 45))/nchoosek(100,45)
ans =  2.8343e-14

The difference certainly is not much, but still significantly larger than eps. So, the question is:
is it relevant?

regards

Thorsten
