JSON protocol doesn't handle negative numbers correctly

[beckettsean]

Negative numbers (I only tested with floats) end up stored as 0:

cat json
{
    "database": "mydb",
    "points": [
        {
            "measurement": "amount",
            "fields": {
                "value_int": -0.001
            },
            "tags": {
                "domain": "123",
                "os": "linux",
                "browser": "chrome"
            }
        }
    ]
}

curl -XPOST 'http://localhost:8086/write' -d @json

> select * from amount
name: amount
tags: browser=chrome, domain=123, os=linux
time                value_int
----                ---------

It works with integers. In a Grafana plot I see always 0 and sometimes falls to -1, -8, etc. (practically only the negative integer values are different by 0).

Seems to be solved in v0.9.1-rc1. From CHANGELOG.MD:
#2919: Unable to insert negative floats

That issue is closed, so I guess this can be closed as well.

Test:

cat json
{
    "database": "test",
    "points": [
        {
            "measurement": "amount",
            "fields": {
                "value_int": -0.001
            },
            "tags": {
                "domain": "123",
                "os": "linux",
                "browser": "chrome"
            }
        }
    ]
}

curl -XPOST 'http://localhost:8086/write' -d @json

> select * from amount
name: amount
tags: browser=chrome, domain=123, os=linux
time                value_int
