JMESPath functions floor and ceil return integer

[BartelNieuwenhuyse]

JMESPath function floor and ceil return a json float number, while the specs and the examples in it suggest that an integer should be returned.

Expected:
floor(`3.7`) -> 3
Actual:
floor(`3.7`) -> 3.0

The cases that fail are failing because a double doesn't have enough precision to represent std::numeric_limits<int64_t>::max() exactly. The upper bound for preserving precision exactly is std::pow(2, std::numeric_limits<double>::digits). Numbers above that limit should remain in double representation. double values above that bound can't be sensibly cast to int types.

I think this is fine, thanks!
