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

2006-12-15 Thread 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 Recipie

This is slightly off-topic, but nonetheless somewhat relevant to these special math functions... Can anyone explain what is the precision of fpc's built-in math functions like sqrt, ln, exp, and so on? According to the online documentation, these take a ValReal argument and return a ValReal resu
