Thanks Prof Ripley. Here is what I meant for "submit a test". I can build and check R source packages for Windows at http://win-builder.r-project.org/, but I am not aware of a link for Mac. I thought this can be useful for those without access to Mac machines. Regards, Zhu Wang

You cannot expect to write out extreme values without some representation error, and adjacent values cannot be read in again. In any case, these values are essentially the same for all R platforms, being mandated by IEC60559.

I know this can be done for Windows, but I'm not sure > for Mac. What does 'submit a test mean'? Any test you write can check the value of Sys.info()["sysname"]: it is "Darwin" on Mac OS X.
