Hello all, I'm trying to get the integer portion of the ceiling of a number using JSTL 1.2 fmt tags on Tomcat 6.x, JavaSE 6.x.
So, if my number is 1.2 , the result expected is 2 (no fractions) or if my number is 1.6 the result wanted is 2 In JavaSE 6 this can be accomplished with NumberFormat http://java.sun.com/javase/6/docs/api/java/text/NumberFormat.html NumberFormat nf = NumberFormat.getIntegerInstance(); nf.setRoundingMode(RoundingMode.CEILING); nf.isParseIntegerOnly(); out.println(nf.format(1.2d)); Math.ceil(1.2d) gives 2.0 I tried the following with JSTL fmt tags, <fmt:formatNumber value="${1.2}" type="number" pattern="#"/> gives 1 <fmt:formatNumber value="${1.6}" type="number" pattern="#"/> gives 2 <fmt:parseNumber value="${1.2}" type="number" integerOnly="true"/> gives 1 <fmt:parseNumber value="${1.6}" type="number" integerOnly="true"/> gives 1 The fmt:formatNumber or fmt:parsNumber do not have a roundingMode attribute http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/fmt/formatNumber.html , This gives: <c:set var="mynum"><%=Math.ceil(1.2d)%></c:set> <fmt:formatNumber value="${mynum}" type="number" pattern="#"/> the expected result 2 . Or the ceiling (and other rounding modes) could be accomplished with a custom tag. I wish the fmt:formatNumber and fmt:parseNumber provide the roundingMode attribute. -Rashmi --------------------------------------------------------------------- To unsubscribe, e-mail: taglibs-user-unsubscr...@jakarta.apache.org For additional commands, e-mail: taglibs-user-h...@jakarta.apache.org
