Arithmetic Operators
The allowable arithmetic operations are shown in the table below in the order of
execution precedence. Parentheses are used to change the order of precedence.
Operations within parentheses are performed first, with the usual order of precedence
being maintained within the parentheses.
Operator Operation Sample Expressions Interpreted As
–,+ Negative or Positive
immediately preceded
by exponentiation
In general, mixed mode expressions are not supported. For example, to compute
A=B*C, where A and B are complex, but C is real, it is necessary to convert C to a
complex number: A=B*CMPLX (C), where CMPLX is described under “Intrinsic
Functions” in this section.
Character Operator
X–Y X(–Y)
** Exponentiation –X**Y –(X**Y)
–,+ Negative or Positive –X – Y (–X) – Y
*,/ Multiplication or
Division
X*Y+Z (X*Y)+Z
+,– Addition or Subtraction X+Y X+Y
The only character operation is concatenation. Its form is shown below.
