A condition is a special \l;expression\u cbot\expr; that returns a \l;boolean\u cbot\bool; value, that can only be either \c;\l;true\u cbot\true;\n; or \c;\l;false\u cbot\false;\n;. With a condition, you can choose f. ex. if the instructions in a \c;\l;while\u cbot\while;\n; loop must be repeated again, or if the instruction in a \c;\l;if\u cbot\if;\n; bloc must be executed.
Here are some operators that you can use in conditions to compare two values :
\c;a == b \n;\c;a\n; equals \c;b\n;
\c;a != b \n;\c;a\n; is different from \c;b\n;
\c;a < b \n;\c;a\n; smaller than \c;b\n;
\c;a <= b \n;\c;a\n; smaller than or equal to \c;b\n;
\c;a > b \n;\c;a\n; greater than \c;b\n;
\c;a >= b \n;\c;a\n; greater than or equal to \c;b\n;
