I can reproduce it, but where is the bug? The expression "Math::BigInt->new(1/2)" gives a zero, just like "int(1/2)". Since zero is an integer, is_int() returns true.

Hi Peter, I'm sorry I misunderstood the API. From the brief bits I had seen I thought it was more of a general purpose numeric library. The penny only dropped when I saw your comment "Math::BigInt->new(1/2)" gives a zero. Regards, PECastro On 12/08/11 18:44, Peter John Acklam via RT wrote: Show quoted text

You probably want to use Math::BigFloat.

This is an invalid ticket. BigInt->new(1/2) is supposed to truncate, per documentation. Please close this ticket.

Hi Brendan It seems I opened the ticket via email submission which doesn't correspond to my cpan user id. I don't have the permissions to close it or reject it. Regards, PECastro On 09/07/12 19:44, Brendan Byrd via RT wrote: Show quoted text

The behaviour is as expected and as documented.
