[issue27094] Floating Point Printing Error with 2+.8553 or 3+.8553

[Seth Norton]

New submission from Seth Norton:

In a basic command line interpreter, adding 2 or 3 to .8553 will cause the result to be displayed as if a rounding error occurred. The number is so small that I expect it is not a mathematical error but rather in how the number is printed.

The displayed answer is 2.8552999999999997.

This also occurs in python 2.7.4. I am running Ubuntu 14.04 (64-bit).
