[fpc-pascal] Special math. functions (erf, erfc, ...)

[Johann Glaser]

Hi!

I'm searching for FreePascal implementations of some special
mathematical functions related to statistics like erf, erfc and some
other cumulative probability functions. Did anybody implement such
functions already (e.g. from the Numerical Recipies)?

Is it allowed to use the Numerical Recipies PDF files (e.g.
http://www.nrbook.com/b/bookcpdf/c6-2.pdf) and type ones Pascal program
one-by-one to the printed source code?

Thanks
  Hansi
