Python 'None' value appearing as -2147483648

QUESTION

Python 'None' value appearing as -2147483648

Asked 2017-Nov-29 at 23:46

I'm reading in a data file from a Paradox database file (.DB) using a module pypxlib.

Whilst reading each row, I write to a CSV.

For some reason, values which expected to be 'None' are appearing as the number -2147483648.

Does anyone know the significance of this number? Why would this error be appearing?

Code below:

Paradox tables contain several numeric types including 'Number' (64-bit floating point), 'Long Integer' (32-bit signed integer), and 'Short' (16-bit signed integer). Each of these types has an in-band value designated to represent 'blank' as distinguished from zero. These are the values that you are expecting to be 'None'.

When the pxlib library and pypxlib wrapper convert Paradox data to Python data types, the in-band value for 'blank' translates to a 1 followed by all 0's. In two's-complement notation this is the value that is furthest from zero in both the positive and negative direction.

If the BDE type was 'Long Integer' then this is indeed represented as -2147483648.

You can use pypxlib like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
