Syntax 1: without a body

<fmt:formatNumber value=”numericValue”

[type=”{number|currency|percent}”]

[pattern=”customPattern ”]

[currencyCode=”currencyCode” ]

[currencySymbol=”currencySymbol” ]

[groupingUsed=”{true|false}”]

[maxIntegerDigits=”maxIntegerDigits” ]

[minIntegerDigits=”minIntegerDigits” ]

[maxFractionDigits=”maxFractionDigits” ]

[minFractionDigits=”minFractionDigits” ]

[var=”varName ”]

[scope=”{page|request|session|application}”]/>

Syntax 2: with a body to specify the numeric value to be formatted

<fmt:formatNumber [type=”{number|currency|percent}”]

[pattern=”customPattern ”]

[currencyCode=”currencyCode” ]

[currencySymbol=”currencySymbol” ]

[groupingUsed=”{true|false}”]

[maxIntegerDigits=”maxIntegerDigits” ]

[minIntegerDigits=”minIntegerDigits” ]

[maxFractionDigits=”maxFractionDigits” ]

[minFractionDigits=”minFractionDigits” ]

[var=”varName ”]

[scope=”{page|request|session|application}”]>

numeric value to be formatted

</fmt:formatNumber>

参数说明：

Value：要格式化的值

Type：怎样进行格式化，如货币 (currency)，百分比 (percent) ，数字 (number)

Pattern：以怎样的格式进行格式化，可以自定义输出格式

currencySymbol：当前货币符号，如￥， $

groupingUsed：是否进行分组输出，会对数字三个一组进行输出

maxIntegerDigits：整数位最大多数位

minIntegerDigits：整数位最少多数位

maxFractionDigits：小数位最多多少位

minFractionDigits：小数位最少多少位

如：代码
