Changes (by kcrisman):
* work_issues: => add erf(sqrt(2)) and erf(45000).n(), formatting,
perhaps speed
Comment:
Here's another thing that should be added, reported by one of the PREP
workshop participants before this patch was in:
{{{
erf(4500).n()
1.0000000
erf(45000).n()
<boom>
}}}
So Pari was not handling big number in erf before. With this patch,
though
{{{
sage: erf(4500).n()
1.00000000000000
sage: erf(45000).n()
1.00000000000000
sage: erf(4500000000).n()
1.00000000000000
}}}
Since none of the doctests in the current patch seem to test "big" real
input to erf, we should add this too.
