Operators, constants, and variables are the constituents of expressions. An expression in TSKL is any valid combination of these pieces. There are three kinds of expressions in TSKL.
Arithmetic expressions can be integral expressions or floating point expressions, depending on the calculation value. In integral expressions, floating point operands will be converted to integer, and vice versa.
String Expressions There is only one operator in string expression, ‘+’, that is, add a string to another string.
Relational Expressions The relational expressions are used to determine the relationship of one quantity to another. The result is true if the value is non-zero, otherwise, it is false.
