The patch should kick out of the integer realm at the boundary of
floating-point precision not at the boundary of integer precision.
Thus,
calculating 2 ^ 63 should result in the value being stored as a
double even
though it could fit into a 64-bit integer.
But this is exactly what it does. The "integer realm" is signed
integers, -2^63 .. +2^63-1 with int64 mode. 2^63 does not fit into a
signed 64-bit integer.
Sorry. I wrote too fast. My point was that even 2 ^ 63 - 1 should
be stored
as a double.
Yes, storing any number outside the range -2 ^ 53 to 2 ^ 53 as a
double would avoid the problem.
