Is this a bug?

ToExpression["3231.432"]

3231.43

I would have expected the following:

3231.432

I am using Mathematica 10.2.0

    $\begingroup$ What do you see when you simply type 3231.43 and hit enter? It's just the number of displayed digits, the 2 is still there. $\endgroup$ Commented Jan 18, 2016 at 15:03

I think this is only a display issue:

If you set

x=3231.432

you also get

3231.42

as a return. However, if you evaluate, say,

x-3000

the missing digit (2) will appear again. I guess Mathematica only displays five significant figures (per default). Hope this helps.
