Arithmetic Functions
Arithmetic Functions that are supported.
      You can use any of the arithmetic functions implemented in the
            java.lang.Math class (http://download.oracle.com/javase/6/docs/api/java/lang/Math.html).
         
In addition to that, the following functions are available:
| Syntax | Details | 
|---|---|
| oxy_add ( param1, ... ,paramN,'returnType') | Adds the values of all parameters from param1toparamN. | 
| oxy_subtract ( param1,param2, ... ,paramN,'returnType') | Subtracts the values of parameters param2toparamNfromparam1. | 
| oxy_multiply ( param1, ... ,paramN,'returnType') | Multiplies the values of parameters from param1toparamN. | 
| oxy_divide ( param1,param2,'returnType') | Performs the division of param1toparam2. | 
| oxy_modulo ( param1,param2,'returnType') | Returns the reminder of the division of param1toparam2. | 
Note
The 
            returnType can be 'integer',
                  'number', or any of the supported CSS measuring types.
               If we have an image with width and height specified on it we can compute the number of pixels on it:
image:before{
 content: "Number of pixels: " oxy_multiply(attr(width), attr(height), "px");
}
