in reply to bc within perl

Hello amudelkaa, and welcome to the Monastery!

I am using bc because the numbers I am using are beyond 64bit in size.

Please note that Perl has core modules to handle arbitrary-size numbers:

Hope that helps,

    I did try BigInt prior to this. That has a restriction of 64bit binary and doesn't support beyond that. I am not sure on BigFloat nor BigRat. The numbers I have in mind are going to be at most 73bits and I couldn't find a better alternative to 'bc' so far.

      Are you sure? 

      perl -Mbigint -wE 'say 12345678912345678912345678912345678912345678912
+3456789123456789 ** 1234'

        So this is bigint and not BigInt? Because when I tried doing the same with BigInt, the data hit the ceiling of xffffffffffffffff.
