I'm trying to convert a string value into a signed long hash value. By doing so, I first convert the string "abcd" to fnv64a hash value which is "18165163011005162717", using the use Digest::FNV::PurePerl module. Thereafter, I am trying to convert this to a signed long by using the Math::BigInt module and the numify method. However, this doesn't appear to be working. I am looking for the long signed value of "-281581062704388899". Is this possible? Thanks.
