fp project:
===========

* a parser and calculator for mathematical formulas
* features:
    - variables (a-z)
    - the ternary operator '?'
    - read formulas from file (line by line)
    - a3  equals a ^ 3
    - 3a  equals 3 * a
    - 1E2 equals 1 * 10 ^ 2
    - a ? b : c equals "IF a != 0 THEN return b ELSE return c"
    - 'long double' precision
* following grammar is implemented recursively:
   T   -> S | S ? S : S
   S   -> P | P + P | P - P
   P   -> O | O * O | O / O | OVar
   O   -> K | K ^ K
   K   -> -K | (T) | Num | Var
   Num -> N | N 'E' Z | N 'E' - Z
   N   -> Z | Z . Z
   Z   -> [0-9]+
   Var -> B | BZ
   B   -> [a-z]

Build:
* to compile the program type 'make'

Install:
* if you want to install the program just copy the binary to e.g. $HOME/bin

Bugs:
* please report bugs to ruester@molgen.mpg.de
