    • JSTL reserved two-bit decimal implementation method
    • Import the following tags at the beginning of the JSP:
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt  "%>   

The value passed in from the background is deltmain. The pattern here is equivalent to DecimalFormat.

<fmt:formatnumber value="${deltmain}" pattern="##.##" minfractiondigits="2" ></fmt:formatNumber>   

The minfractiondigits represents the reserved decimal position, which, if 0, does not preserve decimals.
