# 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: Random numbers
 Random numbers: Random(a), Randstep(a,x)

• Random numbers:  Random(a)
 Random(a) Generates a series of random numbers between 0 and 1 from seed a. Below an example is given F1=Random(0.5) calculated for 100 x-values (F is not a function of x here)

• Random steps with probability x: Ranstep(a,x)
 Generates a random series of  0's and 1's from seed a. The average fraction (or probablity) of 1's is given by x. Below an example is given of an Iteration (100 iterations): F1=F2F2=F1+ Ranstep(0.5,0.3)
