A fork of Python's built-in JSON module, but with added support for decimal.Decimal objects.

Install using:

pip install json_with_decimals

Similar to the proposal given in this issue.

By default, decoded JSON will return decimal.Decimal objects for real numbers, and the encoder supports decimal.Decimal numbers.

Encoding decimals will disable the speedup from the C encoder, so you can temporarily disable decimal support with the support_decimal keyword argument:

import json_with_decimals as json
json.dumps(obj, support_decimal=False)
