Replying to [comment:10 Snark]:
> It's the .binomial part which raises an error : binomial(RR(1140000.78),
23310031) works, but binomial(RR(1140000.78), 23310032) raises the error
(dichotomy).
So, it seems to be some overflow problems in arm? Should we just change
the example
{{{
a = binomial(RR(1140000.78), 42000000)
}}}
to the one below which works on arm? After all, what this is testing is
that the binomial is fast, which is well tested even with something that
is half the size of the previous one
{{{
a = binomial(RR(1140000.78), 23310031)
}}}
Or, does this point to some problem in pari?
