Arithmetic Expressions

An arithmetic expression designates a floating point number. It has the following form:

<term> [<binary-operator> <term>]

A binary-operator is one of the following:

• +    (addition)

• -     (subtraction)

• *    (multiplication)

• /    (division)

• ^    (exponentiation)

 

A term is one of the following:

• Numeric literal. See Numerical Literals.

• Identifier (must be number-valued). See Identifiers and Literals.

• Function invocation (must be number-valued). See Function Invocations.

• Arithmetic Expression. See Arithmetic Expressions.

Arithmetic expressions can be grouped using parentheses.

 

Conventional arithmetic precedence rules are followed:

• Parentheses

• Function Invocation

• Unary operators

• Exponentiation (symbol '^')

• Multiplication/division (symbols '*' and '/')

• Addition/subtraction (symbols '+' and '-')

• Left to right evaluation (textual order)
