[1nickt]: folks, would you say that 1.0 is an integer ?
[Lady_Aleena]: 1nickt, I wouldn't, but I'm not normal.
LanX aggrees, LA isn't normal ;-P
[Lady_Aleena]: LanX, thanks bunches.
[Lady_Aleena]: Rigth now I'm ranting in my head about an old subject.
[1nickt]: Hm, that is, how to prevent Perl from turning 1.0 into 1? I feel sure this must be an faq, but am reading perlnum and not finding the answer ...
[Lady_Aleena]: 1nickt, why does it matter in this case?
[1nickt]: Hm, perhaps this? "Operators which expect an integer force the argument into the integer format."
[1nickt]: Can this be? So print
[1nickt]: ... "expects an integer" ?
