I've poked through my copies of calc.pm and bigint.pm. The offending routine is _log_int (I'm sure you knew that) which requires 2 arguments (the number and the base to which the log is to be taken; I'm sure you knew that, too). It's called from blog in bigint.pm, without the second argument.

I'd agree that this is a bug.

I also noticed that 

#!perl

use strict;

use warnings;

use bignum;

my $n = -1;
print 10.00 **$n  . "\n";

[download]

returns NaN (on Windows; ) for negative values of $n. However, Math::BigFloat works.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
