Compares the variable on the left with the value or variable on the right of the operator. Returns true when the operand on the left is less (smaller) than the operand on the right. Please note that you may compare variables of different data types, but that could generate unpredictable results, it is therefore recommended to compare variables of the same data type including the signed/unsigned type.

- x: variable. Allowed data types: int, float, double, byte, short, long.
