# Functions in 2D and 3D

Functions of the form F(x) and F(x,y) containing up to 20 subfunctions, 30 special functions, 150 numerical and 100 named constants.

Special Functions

# Special Functions (real numbers only!)

 Random numbers

 Modulo function

 Fresnel integrals:

 Exponential integrals and related functions

 Gamma function and related functions

 Riemann Zeta function

 Bessel functions

 Elliptic integrals

 Airy functions

 Probability function

 Distribution functions

Special functions: Poisson probability function
 Poisson probability function    (or probability distribution function): Ppf(a,x)

 Example: The distribution gives the probability for m radioactive decays in some fixed time interval, where a is the mean number of events in that interval. For example: a = np, the product of the the number of radioactive nuclei in a source and the probability for a nucleus to decay in a that interval of time.
