<h1>JSP 2.0 Expression Language - Basic Arithmetic</h1>
|
|
<hr>
|
|
This example illustrates basic Expression Language arithmetic.
|
|
Addition (+), subtraction (-), multiplication (*), division (/ or div),
|
|
and modulus (% or mod) are all supported. Error conditions, like
|
|
division by zero, are handled gracefully.
