Operators

This document is not a comprehensive list of Java or NetRexx operators. The Java books and online documents list all operators of which there are many, including many of the C/C++ operators. You can only learn them by actually using them, in my opinion. This page is to compare Java and NetRexx and warn you up front of some differences before they "gotcha".
 
 
The basic common operations:
+
   Add numeric variables. (see concatenation in table two)
-
   Subtract numeric variables
*
   Multiply numeric variables
/
   Divide numeric variables
>
   Compare numeric variables - op1 greater than  op2
<
   Compare numeric variables - op1 less than op2
==
   (double = sign) Compare for equal values for primitive vars or for the same object otherwise.

 
 
Some basic operations which differ in Java and NetRexx
Java
function of operator
NetRexx
+
Concatenates two strings to form a new string
||
%
Gives remainder of op1 divided by op2
//
!=
Compares op1 and op2 for inequality
\=
!
Logical NOT
\
||
Logical OR
|
none
Compare numbers or padded strings (case insensitive) for equality
=

Note that NetRexx allows "fuzzy" logic comparisons as well as precise comparisons - for example, the strings "  FUZZY  " and "fuZZy       "  are equal when compared via the "=" operator in NetRexx.
