Can you share how did you get the previous 63.994353?. I'm trying the following and I'm getting a different value: a = 2^64 = 18446744073709551616 b = 0x80000000000000 = 36028797018963968 (a - b) / a * 64 = 63.875 Maybe I'm misunderstanding something. _______________________________________________ dev-security-policy mailing list [email protected] https://lists.mozilla.org/listinfo/dev-security-policy
