What is so wrong about it? 128.2 does not have an exact representation
in floating point (just like 0.1 - results in infinite periodic
series). By teh way, floor(128.2 * 100) is 12819 in a C program as
well.

Here's a neat little page that shows IEEE-754 representations of
arbitrary numbers: http://babbage.cs.qc.edu/IEEE-754/Decimal.html
