public class CalcCssFunction<T>
extends AbstractMathCssFunction<T>

Processes the calc() function.

 calc               = "calc(", calc-sum, ")" ;
 calc-sum            = calc-product ,  { [ '+' | '-' ] , calc-product } ;
 calc-product        = calc-value , { '*' , calc-value | '/' , calc-number-value } ;
 calc-value          = number | dimension | percentage | '(' , calc-sum , ')' ;
 calc-number-sum     = calc-number-product , { [ '+' | '-' ] calc-number-product } ;
 calc-number-product = calc-number-value> , { '*' , calc-number-value | '/' , calc-number-value } ;
 calc-number-value   = number | calc-number-sum ;
 

In addition, white space is required on both sides of the '+' and '-' operators. (The '*' and '/' operaters can be used without white space around them.) References:
