calc prime test fails for numbers > 8 million |

Package: emacs
Version: 24.3
On x86_64 GNU/Linux:
emacs -Q -f calc
8000000 RET
k p
-> Wrong type argument: listp, 8000000
Any number >= 8000000 (but < math-small-integer-size) fails in this way.
The problem is the
(% (nth 1 n) 2) 0)
of math-prime-test, which still expects numbers larger than 8000000 to
be in (bigpos ... ) list format, but the limit is much greater than that
these days.
The calc manual is likewise outdated:
19.5.7.1 Data Type Formats
[...]
Large integers are stored as lists of the form `(bigpos D0 D1 D2 ...)'
for positive integers 1000000 or more,

Thanks; this has been fixed in bzr.
(I should increase the size of math-primes-table when I get the chance,
too.)

Ack; I never saw this.
