    I am trying to format a percentage to 2 decimal places and the code I am using is not working.
    <form:input 
     class="calculator-percentage-input"
     value="<fmt:formatNumber value='${percentage}' maxFractionDigits='2'/>"
     path="discount" cssErrorClass="error"
/>

    The value displayed in my input box is (percentage is empty):
    <fmt:formatNumber value='' maxFractionDigits='2'/>
    Can anyone tell me how to just display the value of 'percentage'?

    Solution:

    <fmt:formatNumber var='myDiscountPercentage' value='${discountPercentage}' maxFractionDigits='2'/>

    <form:input
    class="calculator-percentage-input"
    value="${myDiscountPercentage}"
    path="discount" cssErrorClass="error"
    />
