Arithmetic Expressions ()

... $]$] ...
Effect
An arithmetic expression expresses a calculation. The result of an arithmetic expression is a numeric value that exists in the
calculation type that is assigned to the arithmetic expression. In an arithmetic expression arith_exp, the
arithmetic operators +, ,
*, /, DIV, MOD, or ** can be used to join an operand operand1 with one or more operands operand2, operand3 ...
Brackets are also possible. The calculation is based on
calculation rules that depend on the respective calculation type.
Arithmetic expressions can occur in the read positions of
certain statements, in particular on the right side of an
assignment with the assignment
operator =. When used as the operand of the lossless operator EXACT, an arithmetic expression can be checked for a
lossless calculation.
The operand positions operand are general expression positions, that is, numeric data objects,
builtin functions,
functional methods, or compound arithmetic
expressions can be specified. The arithmetic operators +, , *, /, DIV,
MOD, and ** join two adjacent operands. When the expression is evaluated, a numeric value is calculated and linked to the next adjacent operand. The priority of this join depends on the
operators used.
Each operand can be preceded by the signs + or , in any order and separated by one or more blanks. The effect of a plus/minus sign is the same as specifying the expression +1
* or 1 * in its place, which means that a sign has the same priority as a multiplication.
If functional methods or
characterlike
expressions are specified as operands, they are executed from left to right and from inside to outside
before the remainder of the expression is evaluated. The return values are buffered for use in the corresponding operand positions. Here,
characterlike processing functions and
string expressions are only possible as arguments of description functions.
Notes
 It should be ensured that the value of a data object that is also used as an operand is changed
in a specified functional method. Even if such an operand is to the left of the functional method, its value will always be changed by the method before it is evaluated.
 Arithmetic expressions, string expressions, and
bit expressions
cannot be combined. Builtin functions that are used as operands for arithmetic expressions can, however, contain string expressions or bit expressions as arguments.
 A simple arithmetic expression +$ literal, which is comprised of an operator +$, a blank, and an unsigned
numeric literal
literal, has the same value as the corresponding numeric literal +$literal prefixed
directly with a plus/minus sign. However, since the expression is handled like an expression and always evaluated at runtime, the numeric literal should always be used in these cases for performance reasons.
Example
The following program section calculates the hyperbolic sine with the Eulerian formula in the explicit calculation type decfloat34 and with the
builtin function sinh in the implicit calculation type f and displays the difference.
Example
The following program demonstrates the rule specifying how
functional
methods are evaluated in arithmetic expressions. The first calculation sets the variable changing
to 6 and returns the expected result of 9. The result of the second calculation is 15 and not 10 as
might be expected. The functional method is called first and its result 9 is added to the changed value 6 of variable changing and not to its initial value 1.
