   Tests fail for `std::numeric_limits<Int64/Uint64>::min/max()` due to an 
invalid range when a `Scalar[Int64/Uint64]` input is checked against a 
`Scalar[Float64]` output. This failure also occurs for 32-bit floating-point 
values. This error is triggered by the [Arrow testing logic when casting 
integer-to-floating](https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/kernels/scalar_cast_numeric.cc#L195-L209)
 for comparing values in test assertions.
   
   An example test is:
   ```
   this->AssertUnaryOp(floor, this->MakeScalar(min), 
*arrow::MakeScalar(float64(), min));
   this->AssertUnaryOp(floor, this->MakeScalar(max), 
*arrow::MakeScalar(float64(), max));
   ```
   and the error message is:
   ```
   '_error_or_value11.status()' failed with Invalid: Integer value 
18446744073709551615
     not in range: 0 to 9007199254740992
   ```
   The meaning of these numbers is:
   ```
   max(Uint64) = 18446744073709551615
   max(2^53) = 9007199254740992  // mantissa of Float64 = 53
   ```
