IDL platform difference [message #14760]

I have noticed that IDL for Windows and IDL for MacOS seem to handle
some calculations and/or output using float variables differently. I
have a procedure that is carrying out a large calculation and printing
the results to a file. When I run the same procedure on the two
different platforms, I get two different amswers. Example:

On the PC: 4.94e+009 On the Mac: 4.93e+09

I expected the difference in the number of zeroes in the exponent, but
not the change in value. Has anyone ever encountered this before? I
understand the difference is small, but there really shouldn't be any
difference at all. Thanks for any help.
