and these are used in conjunction with brackets: ( ). Variable names are assigned to expressions by using an equal sign, e.g., x = a + b*c; Logical expressions consist of arithmetic expressions, relational and logical operators. They can take the values true = l or false = 0. Relatio...
When all the arithmetic operators in an expression have the same level of precedence, the order of execution is left to right. Expressions that are within parentheses take precedence over all other operations. See Also Data Mining Extensions (DMX) Reference ...
Logical operators are used in control flow such as if expression, when expression, and loops. Example: Logical Operators fun main(args: Array<String>) { val a = 10 val b = 9 val c = -1 val result: Boolean // result is true is a is largest result = (a>b) && (a>c) // resu...
