  With the help of special program package PAREVAL designed in {\sl
Mathematica} system we reproduce values of basic fundamental physical constants
obtained by NIST and recommended by CODATA for international usage since 1998.
In our adjustment we use the input data and methods published by NIST in 1998.
It is shown, that the detected earlier inaccuracy of published by NIST
correlations (that made the NIST 1998&2002 results doubtful) are, most
probably, due to inadmissible independent rounding. The simple estimate of the
critical numbers of decimal digits in the independently rounded correlation
coefficients is obtained. Further independent rounding of ``critically
rounded'' correlations can lead to the non positive semi definite correlation
matrices and hence is inadmissable. It is demonstrated by a few examples that
the poor presentation of the correlated random quantities in the scientific
literature is a common bad practice and is argued (once again) that the common
standard for presentation numerical values of correlated quantities in
publications and sites is urgently and badly needed.
