LP #1130876: pt-table-checksum doesn't process float values on different MySQL versions

**Reported in Launchpad by Aleksandr Kuzminsky last update 28-04-2015 11:41:19

There is a float column in a table.

In version 5.0 it's represented as:
points_first: 1e+06

In 5.5 -
points_first: 1000000

Although the number is the same pt-table-checksums treats the values as different.
