Size of number in scalar

[Christopher D . Lewis]

Someone posted a question as to the size of number which a scalar would tolerate. When I wanted to know what size boundaries I faced in certain variable types in C, I wrote a little program that added 1 to a variable until n+1 was less than n, at which point I concluded the variable had been rolled over to its start again. Perl seems to tolerate quite a bit of this, as the app has been churning away, printing every so many number just to let me know where it's at, and it recently went past two hundred billion (I cheated and am incrementing by 1000 instead of 1, because I got impatient incrementing by one). $scalars in perl handle big numbers ... and maybe Perl notices when a boundary is being crossed and reconstitutes the number?

Take care,
Chris
