# I have the fix; filing for records If large-enough values are used for multiplication, we get 0 instead of correct results: <Zoffix> m: say (my int $ = 2**32) * (my int $ = 2**63) <camelia> rakudo-moar 62d838: OUTPUT«0» <Zoffix> m: say (my int $ = 2**62) * (my int $ = 2**62) <camelia> rakudo-moar 62d838: OUTPUT«0» The fix is to add `or $a == 0 || $b == 0 ?? 0 !! Failure.new(X::Numeric::Overflow.new)` after the calculation in https://github.com/rakudo/rakudo/blob/62d8382/src/core/Int.pm#L262 However, that currently won't work entirely due to RT#129811: https://rt.perl.org/Ticket/Display.html?id=129811
