Subject: [PATCH] [SQL] Using safe floating-point numbers in doctest
Test code in `sql.py` tries to compare two floating-point numbers directly, and cased [build failure(s)](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/18365/consoleFull).
[Doctest documentation](https://docs.python.org/3/library/doctest.html#warnings) recommends using numbers in the form of `I/2**J` to avoid the precision issue.
Author: Cheng Lian <lian.cs.zju@gmail.com>
Closes #1925 from liancheng/fix-pysql-fp-test and squashes the following commits:
0fbf584 [Cheng Lian] Removed unnecessary `...' from inferSchema doctest
e8059d4 [Cheng Lian] Using safe floating-point numbers in doctest
