TanookiToad opened a new issue, #364:
URL: https://github.com/apache/arrow-julia/issues/364
If a float-type element in ```PooledVector{Real, UInt32, Vector{UInt32}}```
is replaced by an integer, Arrow will incorrectly save this value.
```
using Arrow, DataFrames, PooledArrays
df = DataFrame(x = PooledArray(Vector{Real}([1.0])))
df[1, 1] = 2
Arrow.write("test.arrow", df)
Arrow.Table(io) |> DataFrame
```
The following code incorrectly saves 11 as 1.0e-323.
```
1×1 DataFrame
Row │ x
│ Float64
─────┼──────────
1 │ 1.0e-323
```
