Compilateur

Features

• Management of operations on rationals: addition, multiplication, division, subtraction, power.

• Rational simplification and rounding management (e.g.: sim, [-], %).

• Integer operations: lcm, gcd.

• Variable declarations (integer, Boolean, rational).

• Variable assignment and reassignment.

• Rational expression display.

• Condition and loop management.

• Boolean expressions with lazy evaluation.
  

Source language

The language used in this project is a rationals language, with three types of expressions:

• Integers: relative numbers that can be positive or negative.

• Rationals: numbers in the form a/b, where a is the numerator and b the denominator.

• Booleans: Boolean values for conditions and loops.

  
  

Syntax

• Operations on rationals: addition (+), subtraction (-), multiplication (*), division (:), power (**), simplification (sim), rounding ([-]), percentage (%).

• Instructions :

  • Assignments (=),

  • Display regular expressions with afficher(exprR),

  • Conditional instructions (? :),

  • Loops (repeat ... until).
