how to format a percentage

[Bhaarat Sharma <bh...@gmail.com>]

I have the following in my properties file:
format.percent = {0,number,##0.00'%'}

But the following code doesnt work and always gives 0.00%

<s:text name="format.percent"><s:param value="%{( (50 / 200) *
100)}"/></s:text>
...evaluates to <s:text name="format.percent"><s:param value="%{( (.25) *
100)}"/></s:text>



However, the following code does work...

<s:text name="format.percent"><s:param value="%{( (200 / 50) *
100)}"/></s:text>
...evaluates to <s:text name="format.percent"><s:param value="%{( (4) *
100)}"/></s:text>

What is going on here? why dont decimals work?

have you tried<s:text name="format.percent"><s:param value="%{( (50.0 /
200.0) *100.0)}"/></s:text>

without the decimal OGNL might treat your numbers as integers and there for
you get 0.

I havent test it out but thats what I used to do for JSTL
