Description

After upgrading from Couch 0.10.1 to 0.11.0, big integers are now being returned by couch as decimals. This is a change from the previous release.

Here's a curl session demonstrating the problem:

curl -X POST http://localhost:5984/msdtest -d '

{"num":123456789123456789}

'

{"ok":true,"id":"8d211c89d80d14972af7cb93e71754bc","rev":"1-fce9e6cc4e72866f75aeadbaed1a65c9"}

curl http://localhost:5984/msdtest/8d211c89d80d14972af7cb93e71754bc

{"_id":"8d211c89d80d14972af7cb93e71754bc","_rev":"1-fce9e6cc4e72866f75aeadbaed1a65c9","num":123456789123456780.0}

In Futon, the 'num' value does not have a decimal.

It seems like the problem occurs with large numbers.  Here's another curl
where the num is not made into a decimal:

curl -X POST http://localhost:5984/msdtest -d '

{"num":123456789}

'

{"ok":true,"id":"8d211c89d80d14972af7cb93e7175daf","rev":"1-039a59b36e40b4216eac91872eed4645"}

curl http://localhost:5984/msdtest/8d211c89d80d14972af7cb93e7175daf

{"_id":"8d211c89d80d14972af7cb93e7175daf","_rev":"1-039a59b36e40b4216eac91872eed4645","num":123456789}

Here's a session from 0.10.1 demonstrating the problem did not exist in that release:

curl -X POST http://localhost:5984/msdtest -d '

{"num":123456789123456789}

'

{"ok":true,"id":"fcd6d8fca421023581a608758a0abe35","rev":"1-fce9e6cc4e72866f75aeadbaed1a65c9"}
