operator - cannot be applied to java...

2004-02-06 01:38

I am trying to calculate the difference of 2 columns:

variabile type is double (as the comuns are)

Expresion:

$F{val_mon} - $F{val_mon_inc}

....

When running the report I get this error:

 

operator - cannot be applied to java.lang.double, java.lang.double:

value = (java.lang.Double)(((java.lang.Double)field_val_mon.getValue()) - ((java.lang.Double)field_val_mon_inc.getValue()));

 

 

I do not know what is the problem : everything is DOUBLE - why can't HE operate the difference ?

 

Thank You,

Adrian Din

Found it:

new Double( $F{val_mon}.doubleValue() - $F{val_mon_inc}.doubleValue ())
