Inconsistent Mean Calculation [message #30841]

I have 5000 frames of video in a NetCDF file, and I want to calculate
the average of frame 2557. I have read the video file into both IDL
v5.1 and
Matlab v6.1. Additionally I have extracted frame 2557 and copied it
into Excel. Here are the mean calculations I get for this frame:

Matlab: 4092.6805
Excel: 4092.6805
IDL: 4093.6165

Can anyone offer any suggestions as to why the IDL calculation is
different? Maybe there is a bug in IDL 5.1? Yeah I know it's a
really old version. :)
