Moin,
On 14-Sep-01 Gerrit Haase tried to scribble about:

It is the second of these two tests:
$z = 1050000000000000; # may be int on systems with 64bit?
$x = Math::BigInt->new($z); ok ($x->bsstr(),'105e+13'); # not 1.03e+15
$z = 1e+129; # definitely a float (may fail on UTS)
$x = Math::BigInt->new($z); ok ($x->bsstr(),$z);
It seems that Cygwin can not handle 1e+129 :-(
What is the biggest number Cygwin can handle (aka what is the float size
there)?
I think I need to adjust Calc.pm for this, too. The code to determine the
maximum safe integer number base migh guess wrong.
The Math::Pari failure is something I can do little about, because if Perl
(via underlying OS/lib) can not handle so large numbers, I might have no
recurse except skipping that test there :-/
Or, could I just use 2^64 and hope that it is not an integer (no 128 bit
systems out there ;), but always fits into a float on any system?
The test is not critical, anyway.
Cheers,
Tels
