    z-distribution function in C

    I'm doing some simple confidence interval statistics. I need to calculate normal curve areas. Where can I find a C function that calculates the z-distribution?

    Thanks,
    Peter

    Most people start with google
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I did check google and always do. Should I state that at the top of a new question? It is not easy to find C code for the inverse error function.

    Yeah, but did you find anything describing the algorithm?
