Subject: [ruby-core:65323] [ruby-trunk - Bug #10306] BigNum error

Issue #10306 has been updated by Tsuyoshi Sawada.


Cannot be reproduced on ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-linux]. I get the correct result:

    (1000000000 ** 99).to_s.count("0")
    # => 891
    1000000000.to_s.count("0") * 99
    # => 891

Some calculations are wrong when dealing with large bignums.

For example, try 1000000000 ** 99, the result is obviously not right.
