double_ parser is less precise than atof

The following code demonstrates a small loss of precision using qi. I'm using
VS 2013 and boost 1.60.0. The problem is shown near the end where an int64
is converted to double.

The main problem for me is that I'm trying to replace an existing parser
with qi. The small differences in precision are causing differences in our
regression test suite.
