在应用程序开发中,如果内容过长,想截取一定长度字符,然后补充"..."jstl1.1引入了一个fn.tld的标签,用于处理字符,如获得字符length,substring,indexof,endWith,lowcase实现截取字符串如:JSTL与Struts的结合(八)7 Functions标签库称呼Functions标签库为标签库,倒不如称呼其为函数库来得更容易理解些。因为 Fu Function...
math.pow(x, y): 返回x的y次幂。 math.sqrt(x): 返回x的平方根。 3)常用数学函数 math.ceil(x): 返回大于或等于x的最小整数。 math.floor(x): 返回小于或等于x的最大整数。 math.fabs(x): 返回x的绝对值。 math.factorial(x): 返回x的阶乘。 math.modf(x): 返回x的整数部分和小数部分。 4)...

the primitive number types. ThePrintStreamandDecimalFormatclasses provide methods for writing formatted numerical output. Finally, theMathclass contains mathematical functions to complement the operators built into the language. This class has methods for trigonometric functions, exponential functions, and so ...
java.math.BigDecimal java.math.BigInteger Floating-point types should never be used in primary keys. If you use a generated primary key, only integral types will be portable. A primary key class must meet these requirements. The access control modifier of the class must bepublic. ...
