    Parameters

    lhs

    The first value to add.

    rhs

    The second value to add.

    The sum of the two arguments must be representable in the arguments’ type. In the following example, the result of 21 + 120 is greater than the maximum representable Int8 value:

    var x: Int8 = 21
x += 120
