<h1 class="topictitle1">Arithmetic expressions</h1>
|
||
|
|
<div><p>The operands in an arithmetic expression must be decimal constants
|
||
|
|
or decimal or integer CL variables. </p>
|
||
|
|
<div class="section"><p>An arithmetic operator (only in symbolic form) must be between
|
||
|
|
the operands. The results of all arithmetic expressions are decimal values,
|
||
|
|
which may be stored in a CL variable.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> The division operator (/) must
|
||
|
|
be preceded by a blank if the operand that precedes it is a variable name.
|
||
|
|
(For example, <samp class="codeph">&A /2</samp>, <em>not</em> <samp class="codeph">&A/2</samp>.)
|
||
|
|
All other arithmetic operators may optionally be preceded or followed by a
|
||
|
|
blank.</div>
|
||
|
|
<p>Arithmetic operands can be signed or unsigned;
|
||
|
|
that is, each operand (whether it is a numeric constant or a decimal or integer
|
||
|
|
CL variable) can be immediately preceded by a plus (+) or minus (-) sign,
|
||
|
|
but a sign is not required. When used as a sign, no blanks can occur between
|
||
|
|
the + or - and its value. For example, a decimal constant of 23.7 can be expressed
|
||
|
|
as +23.7 or -23.7 (signed) or as 23.7 (unsigned).</p>
|
||
|
|
<p>The following are
|
||
|
|
examples of arithmetic expressions:</p>
|
||
|
|
<pre>(&A + 1) (&A + &B -15)
|
||
|
|
(&A - &F) (&A+&B-15)
|
||
|
|
(&A + (-&B))</pre>
|
||
|
|
<p>If the last non-blank character on a line
|
||
|
|
is a + or -, it is treated as a continuation character and not as an arithmetic
|
||
|
|
operator.</p>
