binary writeFormat and timePrecision and writePrecision
 

If I set writeFormat to binary, are there any meaning of timePrecision and writePrecision?

Thanks.

I know this is an old question, but I had the same doubt so I'm giving an answer here:

I would say that when you use binary output the writePrecision value will be ignored (I also tested that, the md5sums of both output files remain the same).


However, the timePrecision is not affected by the choice of binary output because timePrecision only affects the directory names.

writePrecision still has some meaning when using binary as writeFormat.

I have observed that run-time post-processing data, e.g. data extracted by functionObjects, always gets written in ascii format.
