# Writing arithmetic expressions

As expressions become more complicated, the pencil and paper solutions require a little more work. The result is assigned the type of the left operand.

In elementary school you learned how to evaluate simple expressions that involve the basic binary operators: addition, subtraction, multiplication, and division. Character Substrings A character substring is a contiguous sequence of characters that is part of a character data item. Ordinary symbols specified in arithmetic expressions must be defined before the arithmetic expression is encountered, and must have an absolute value. Character expressions are built up from the following simple elements: character constant or symbolic name of a character constant character function reference character array element reference character substring reference Construct complicated character expressions from one or more of these elements using the concatenate operator and parentheses. Because of this simplicity, some popular hand-held calculators use postfix notation to avoid the complications of the multiple parentheses required in nontrivial infix expressions. When raising a value to an integer power, the integer is not converted. You learned in your mathematics classes that multiplication is done before addition. We now apply this operator to the two previous operands. An arithmetic expression must not contain two terms in succession. An arithmetic expression can have one or more unary operators preceding any term in the expression or at the beginning of the expression. The result of an integer division operation is a value of type integer, referred to as an integer quotient.

It is easy to make a mistake writing or interpreting an infix expression containing multiple nested sets of parentheses. A character constant expression cannot contain variable, array element, substring, or function references. The operator in an infix expression is written in between its operands.

When raising a value to an integer power, the integer is not converted. Character Substrings A character substring is a contiguous sequence of characters that is part of a character data item. Exponentiation Exponentiation is an exception to the above rules for mixed-mode expressions.

## Writing arithmetic expressions

An arithmetic-valued function is a term. Character Substrings A character substring is a contiguous sequence of characters that is part of a character data item. The result is assigned the type of the left operand. For example, The result of an integer division operation is a value of type integer, referred to as an integer quotient. When an expression contains multiple operators such as the one shown here, we need to use a set of rules to determine which operation to carry out first. In elementary school you learned how to evaluate simple expressions that involve the basic binary operators: addition, subtraction, multiplication, and division. The one we saw most recently. An arithmetic expression can contain up to 24 unary and binary operators, and is limited to levels of parentheses. The integer quotient is obtained as follows: If the magnitude of the mathematical quotient is less than one, then the integer quotient is zero. Ordinary symbols specified in arithmetic expressions must be defined before the arithmetic expression is encountered, and must have an absolute value. Exponentiation Exponentiation is an exception to the above rules for mixed-mode expressions. Rules for coding arithmetic expressions HLASM Language Reference SC Here is a summary of coding rules for arithmetic expressions: Unary operating on one value operators and binary operating on two values operators are allowed in arithmetic expressions.

These are called binary operators because they each operate on two operands. When an expression contains multiple operators such as the one shown here, we need to use a set of rules to determine which operation to carry out first.

An arithmetic expression can contain up to 24 unary and binary operators, and is limited to levels of parentheses.

An arithmetic expression can have one or more unary operators preceding any term in the expression or at the beginning of the expression. If the magnitude of the mathematical quotient is greater than or equal to one, then the integer quotient is the largest integer that does not exceed the magnitude of the mathematical quotient and whose sign is the same as that of the mathematical quotient.

### Arithmetic expression math

These expressions are written using a format known as infix notation. The one we saw most recently. You learned in your mathematics classes that multiplication is done before addition. The first item, 6, is an operand, so we go on. For example, Ordinary symbols specified in arithmetic expressions must be defined before the arithmetic expression is encountered, and must have an absolute value. A character constant expression cannot contain variable, array element, substring, or function references. It is easy to make a mistake writing or interpreting an infix expression containing multiple nested sets of parentheses. A substring name has one of the following forms: var [e1]:[ e2] The following arguments are used: var. There are no precedence rules to learn, and parentheses are never needed.

The one we saw most recently. The integer quotient is obtained as follows: If the magnitude of the mathematical quotient is less than one, then the integer quotient is zero.
