eval: Fix range check of double during conversion to int

2⁶⁴-1 and 2⁶³-1 are not representable as double and get rounded to
2⁶⁴ and 2⁶³ respectively, which are outside the range of 64-bit
[u]int.

This causes undefined behavior when a constant expression is evaluated
that involves a conversion of a very large or small value to an
integer type.

To fix this, change the > to >= and use constants representable as
double.
