- Description of the various user-defined functions for !Evaluate.
-
- If you add any functions to the function-library called 'Functions', please
- describe the function, ie. its calling convention, parameters, result,... in
- this text-file, so that other users of !Evaluate may benefit from your ideas!
- Please try to make your function-description conform with that of the first
- seven descriptions...

- Descriptions of the User-defined Functions:
- *******************************************
-
- MAX : Parameters : two reals x,y
- Returns : real, being the maximum of x and y
- Syntax : MAX(x,y)
- Example : MAX(4.02,10) = 10
-
- MIN : Parameters : two real x,y
- Returns : real, being the minimum of x and y
- Syntax : MIN(x,y)
- Example : MIN(-9.3,MAX(4.02,10)) = -9.3
-
- FAC : Parameters : one integer x
- Returns : integer, being the factorial of x
- Syntax : FAC(x)
- Example : FAC(5) = 120
-
- SEC : Parameters : one real x
- Returns : real, being the secans (1/COS) of x
- Syntax : SEC(x)
- Example : SEC(FAC(4)) = 2.357495262
-
- COSEC : Parameters : one real x
- Returns : real, being the cosecans (1/SIN) of x
- Syntax : COSEC(x)
- Example : COSEC(12) = -1.863679599
-
- MANDEL : Parameters : two reals x and y (components of x+yi)
- Returns : real, being the potential -relative to the
- Mandelbrot Set- of the point x+yi
- Syntax : MANDEL(x,y)
- Example : MANDEL(-1.4,.3) = 0.01159676471
-
- ITERATE : Parameters : a string f$, a real x and an integer m
- Returns : real, being the result of the function f$ iterated
- m times, with initial value x
- Syntax : ITERATE(f$,x,m)
- Example : ITERATE("COS",123,100) = 0.7390851332
