6.2 Operator Precedence

When an expression contains more than one operator, BHT-BASIC performs the operations

in the standard precedence as shown below.

Precedence

Parentheses ( )

Parentheses ( ) Parentheses ( )

Parentheses ( )

The parentheses allow you to override operator precedence; that is, operations

enclosed with parentheses are first carried out.

For improving the readability of an expression, you can use parentheses to separate

two operators placed in succession.

String operations

When more than one operator occurs at the same level of precedence, the BHT-BASIC

resolves the expression by proceeding from left to right.

a=4+5.0/20*2-1

In the above example, the operation order is as follows;

5.0/20 (=0.25)

0.25*2 (=0.5)

4+0.5 (=4.5)

4.5-1 (=3.5)
