Hm. Attempting calculate 1 - 1/2**128 using my calculator just returns 1.

So then I tried Math::BigFloat, and still got just 1. What Am I doing wrong?

use Math::BigFloat;

$moritzFactor = Math::BigFloat->new( 1 )->bsub(
    Math::BigFloat->new( 1 )->bdiv(
        Math::BigFloat->new( 2 )->bpow( 128 )
    )
);

print $moritzFactor;
;;
1

[0] Perl> print $moritzFactor->bstr;;
1

[0] Perl> print $moritzFactor->bsstr;;
1e+0
