The **dumb** or **simple lookup** is a program that looks in the huge
tables to see if there is a match between the input X (your number) and an
entry in the tables.

- K+p/q and K-p/q with p/q in F24, this is the Faray fractions or order 24 (omitting the 0 and the 1).
- K*p/q with p/q in F24.
- sin(K), cos(K), tan(K), log(K),exp(K).
- Elementary variations like (K-1)/(K+1), sqrt(K+1), ...
- Various powers of K like K^(1/2), K^(1/3), K^(2/3)...
- Variations with Pi and K.

We had to be sure that the output is always positive, so this is why there are 'abs' in many of them. Also we had to choose to limit the input (X) to be between 1/1000 and 1000.
