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 result: e.g.: function sqrt(d: ValReal):ValReal; But what exactly is a ValReal? Real? Double? Extended? It would be ideal if these math functions would take arguments of different precision and return results in the same precision. Is that what happens? I am asking because I need extended precision versions of sqrt, etc, and I do not believe fpc provides that (at least by default). I have seen the mpcalc unit, but I was hoping for a solution that doesn't involve a special unit (with special coding). Thank you for any information or suggestions...
