I think you are confusing three quite distinct issues. 

-correlate-, -pwcorr- and -spearman- all calculate results to machine precision.  

Each of them has their own choice of display format, which happen to be identical at %7.4f. 

If you pick up the correlation in r(rho), then what display format you use to print that out elsewhere is up to you. 

I wonder what use 5th and higher decimal places can be for correlations in any case.

Still there's one question left to the code: How can I determine the 
number of decimals the coefficients shall be rounded to?
(pw)corr and spearman do not seem to explicitly provide for such an option.
