Subject: [integer] - [rational] expression problem
hi,i think i might find a integer minus rational problem. when i execute this perl -Mbigrat -e 'print 1 - 1/2' perl doesn't give the answer,but use more and more memory,and a lot of cpu time but 1 +- 1/2 or 1/1 -1/2 can work perl version 5.12.2 bigrat version 0.25 uname -a Linux gentoo 2.6.35-gentoo-r10-smp #1 SMP Thu Oct 7 16:59:48 CST 2010 i686 Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz GenuineIntel GNU/Linux the detail of version is in the attached file. thanks

I have verified that this occurs on my system: perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi $ modversion Math::BigInt 1.89 $ modversion bigrat 0.23

It gives a NaN (which isn't correct either) on Cygwin with bigrat v0.23: $ perl -Mbigrat -wle 'print 1 - 1/2' NaN $ perl -Mbigrat -wle 'print bigrat->VERSION' 0.23
