floating point math bug in make_subplots

[chubukov]

import plotly as py
from plotly.tools import make_subplots
n=80
make_subplots(n,1)

<stacktrace snipped,>

ValueError:
Invalid value of type 'builtins.float' received for the 'domain[1]' property of layout.yaxis
Received value: 1.0000000000000004

The 'domain[1]' property is a number and may be specified as:
  - An int or float in the interval [0, 1]

plotly version 3.0.0rc11
happens with python 3.5.4 and python 3.6.3

curiously, n=100 works fine! But most other values >40 fail for me

Hi @chubukov ,

I think you're hitting this issue: #1050

It was fixed in version 3.0.2. Could you please update and try again?

Thanks!

@jonmmease Yep, seems to be fixed. Thanks.
