Re: Change rounding mode

I would like to change the formatting that freemarker uses to show a
Double with only two decimal positions (${x?string("0.##")}). I want
freemarker to round it with the half-up rule.

Hello,

I would like to know if there is an easy way to change freemarker's
default rounding mode. As the freemarker manual says:

"Following the financial and statistics practice, the rounding goes
according the so called half-even rule, which means rounding towards the
nearest ``neighbor'', unless both neighbors are equidistant, in which
case, it rounds towards the even neighbor..."

But I would like to use HALF_UP.

Out of curiosity, why?

Otherwise I don't think it's possible in FreeMarker, since it's number
formatting is what the Java platform provides, and DecimalFormat uses
half-even rounding, and it isn't configurable in this regard. That
said, you couldn't even do that in a Java program. So, blame the J2SE
API guys... ;)

Of course, you could write the function for this easily:

<#function n3 n>
<#return ((n*1000)?round/1000)?string>
</#function>

Does anybody know if it's configurable?

Thanks!
