String Concatenation

The binary operator . creates a string that is the concatenation of the left-hand operand and the right-hand operand, in that order. If either or both operands have type int, their values are converted to type string. Consider the following examples:

"foo"."bar"; // "foobar"
"A" . 25;    // string result with value "A25"

note

String concatenation can only be performed on string and int arguments, i.e., not on arguments of type float, etc.
