This particular error is listed as an “FPCP Underflow”.
Translated, that means: the Floating Point Control Processor (FPCP) calculated a number that was too small to store.
For instance, if you multiply 0.0000000000001 by itself you get 0.0000000000000000000000001.
The number is so small that the space set aside in the computer for the result isn’t adequate to hold the number accurately.
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.
