Comparison Operators

| e >= f | e is greater or equal to f |

let (e, f) = (1, 100);
let greater = f > e;        // => true
let less = f < e;           // => false
let greater\_equal = f >= e; // => true
let less\_equal = e <= f;    // => true
let equal\_to = e == f;      // => false
let not\_equal\_to = e != f;  // => true
