This particular error is listed as “FPCP Inexact Result”.
Translated, that means: the Floating Point Control Processor (FPCP) calculated a number that wasn’t exact.
For instance, if you divide 1 by 3 you get 0.333... The number will always have a remainder no matter how many decimal places you add to the result.
The error could indicate that your System file is corrupted.
What to do
If you suspect that the System file is corrupted, try re-installing it. If that fails to solve the problem, you are probably having a hardware failure. The System file can appear to be corrupted because of bad RAM or a bad disk. These possibilities can only be evaluated with certainty by an Apple Repair shop. Consider having your system examined if you don't feel capable of doing it yourself.
