+    // The operators works like in the C language
+    // For example:
+    3 == 2; // => 0 (NO)
+    3 != 2; // => 1 (YES)
+    1 && 1; // => 1 (Logical and)
+    0 || 1; // => 1 (Logical or)
+    ~0x0F; // => 0xF0 (bitwise negation)
+    0x0F & 0xF0; // => 0x00 (bitwise AND)
+    0x01 << 1; // => 0x02 (bitwise left shift (by 1))
