It would not give a very good answer unless you actually mean to call floor() on your decimal value. A better solution would be to replace line 10: return "%d" % obj with return obj.to_eng_string() this way you still get a stringified version of your decimal, without rounding errors or forcing it to an integer. Also, since simplejson 2.1.0, you can pass 'use_decimal=True' to simplejson.dumps(), which will handle this for you without needing to add this handler. django.utils, though, has 2.0.7 as of 1.2 , so this technique is still useful.
