    There's only a random number generator.
    Does anyone know if it's possible to "code" one in a script?

    THANKS

    Calculating something really accurate can be difficult due to the limitations of integer arithmetics. The simplest method is maybe to make use of the Central Limit Theorem and make an approximation by calculating the average of a small number of (I've seen people use 12) uniformly distributed random numbers.

    See: http://www.dspguide.com/CH2.PDF
    For help with a script implementation I recommend you bring the question over to the VI-Control forum. This seems like a good subject to discuss with Big Bob there who has already implemented functions like sin, cos and log in KSP.

    Hey Kotori,
    Wow, thanks so much for the help. I'll look at the DSP Guide chapter (which I didn't know about btw, so THANKS) and head over to VI.
