Hello everybody: I am planning to use a few PASCAL programs for certain matrix manipulations. In the past, these subroutines were run in Turbo Pascal 6 or 7, with good numerical accuracy. Because the manual says that gpc doesn't pass the "paranoia" test, I have become a bit wary about running them in gpc. All subroutines are written in ISO PASCAL, and perform things such as: Cholesky decomposition, singular value decomposition, inversion etc. All variables are declared either as INTEGER or REAL. If memory serves me, in TP this means a 10-11 decimal digit mantissa for real numbers. Does anybody have experience in this regard? Am I being too "paranoid"? Thanks in advance, Francisco S.
