How to set the variable to 2 decimal places

Question

I'm creating a variable in JSTL using

<c:set var="billableTime" value="${ps.computedAmount}" />

My problem is ps.computedAmount is not a 2-digit decimal and I want the ps.computedAmount to be rounded off to 2-decimals before assigning to billableTime. I know how to display a 2-digit number in JSTL by using

<fmt:formatNumber type="number" minFractionDigits="2" maxFractionDigits="2" value="${ps.computedAmount}" />

But my problem is about assigning a 2-digit value to a JSTL variable.

Answer 1

I think you can do it like this:

<c:set var="billableTime"><fmt:formatNumber type="number" minFractionDigits="2" maxFractionDigits="2" value="${ps.computedAmount}" /></c:set>

Answer 2

<fmt:formatNumber var="formattedBillableTime" type="number" minFractionDigits="2" maxFractionDigits="2" value="${ps.computedAmount}" />

<c:set var="billableTime" value="${**formattedBillableTime**}" />
