thinBasic has a full range of operators, including arithmetic operators, comparison operators, concatenation operators, and logical operators.

 

Operator Precedence

 

When several operations occur in an expression, each part is evaluated and resolved in a predetermined order called operator precedence. You can use parentheses to override the order of precedence and force some parts of an expression to be evaluated before others. Operations within parentheses are always performed before those outside. Within parentheses, however, standard operator precedence is maintained.

 

When expressions contain operators from more than one category, arithmetic operators are evaluated first, comparison operators are evaluated next, and logical operators are evaluated last. Comparison operators all have equal precedence; that is, they are evaluated in the left-to-right order in which they appear. Arithmetic and logical operators are evaluated in the following order of precedence.

 

Arithmetic precedence

Description

Exponentiation

^

Unary negation

-

Left byte shift

<<

Right byte shift

Multiplication

Division

/

Integer division

Addition

+

Subtraction

-

 

When multiplication and division occur together in an expression, each operation is evaluated as it occurs from left to right. Likewise, when addition and subtraction occur together in an expression, each operation is evaluated in order of appearance from left to right.
