compare float?

["Skriloff, Nicholas" <Sk...@darden.virginia.edu>]

3 Questions:

1) We have been using velocity 1.3.1-rc2 and have a requirement where we
need to compare floats in velocity templates.  So we need to do
something like

 #set($afloat=$floatObject.gpa)

 #set($gpaWarning = 2.7)

 #if ($afloat <= $gpaWarning)

academic probation letter....

 

Can this be done in 1.5-dev?  If we need to put the gpaWarning value
into context, we can do that if it cannot be declared in the template.
Is that needed? 

 

2) We have quite a bit of code that depends on 1.3.1-rc2, is 1.5-dev in
a stable state? 

 

3) What is the URL to get the Velocity 1.5-dev version? 

 

--------------------------------------------------

The unreleased Velocity 1.5-dev (grab the nightly snapshot of the source


code) handles floats and all other number types.

 

Best,

WILL

Yes it can, so no it's not.  As an alternative, you can create a
$floatObject.isGpaUnderWarningValue() method.  :)

The developers are trying their best to keep the code base working.  I
would trust it, but it's up to you to decide.
