in reply to Adding really big numbers

Which version of Perl are you using? It works just fine for me on 5.16.1. Using bigint, I get values for every integer. Using bignum, I get values for every int and decimal (except for trailing zeroes). Without an extra module, anything over 20 digits defaults to scientific notation with 15 digits of precision.

Update: Here is some info on largest positive/negative integers that can be nadled by different setups w/o using modules: Re: maximum value of a scalar

    I'm using 5.14. I agree, it's strange.
      Odd. Works fine for me on 5.14.2. What is your operating system?
        Oddly enough, with Math::Bigint, it's working. Bizarre...
        MS Windows 7.
