Subject: $x -> bmodpow(1, 1) fails when $x is large
Download (untitled) / with headers
text/plain 394b
Mathematically, x^1 (mod 1) is 0 for all x, but this fails in Math::BigInt when x is large: $ perl -MMath::BigInt -wle 'print Math::BigInt -> new("1e50") -> bmodpow(1, 1)' 100000000000000000000000000000000000000000 This bug has been present since the bmodpow() method was introduced in version 1.58. I have tracked down the problem to be (yet another bug) in Math::BigInt::Calc -> _modpow().
