How to compare numbers with strings

Hello,

I have a problem.

I want do something like:

    #if ( ( $col.Type == "VARCHAR") && ( $col.getSize() > 255 ))
        #set ( $type2 = "BLOB" )
        #set ( $size = "" )
    #end

The expression:
($col.getSize() > 255 )
does not work.


($col.getSize() == "4000" )
works with $col.getSize() is 4000

but 
($col.getSize() == 4000 )
does not work.


How can I compare a int with a String?

regards
Martin

  Could it be that $col.getSize() returns a long and not an int?
Velocity cannot deal with longs :(
So the hack Denis proposed would be the last option.

Well, there is a somewhat updated comparison available since yesterday
night on http://freemarker.org/fmVsVel.html ... just it is from the
authors of FM... :)

Velocity + Turbine

Posted by Bobirkhon Ismailov <bi...@uzavtoyul.uz>.
Hello, I have read about Velocity and its commitment to Turbine. I would
really appreciate if you point me to a manual describing the use of
Velocity with Turbine.  

Also, I am new to Velocity and templating languages in general, so I'd
like to know your comparison of Velocity to other TPLs, in particular to
FreeMarker.

Thank you.

Could you have the col size put in the context as an integer instead of 
a string?
Alternatively, you could use this little hack:

#set ( $number = 1 ) ## Gives access to java.lang.Integer methods
#if ( ( $col.Type == "VARCHAR") && ( $number.valueOf($col.getSize()) > 
255 ))

Cheers,
-- Denis.
