185、Excel函数之财务函数五--投资评价函数2内部收益率函数IRR
      内部收益率IRR是internal rate return的缩写，返回由一系列现金流的内部收益率。它就是使净现值为0的折现率。反应项目的盈利能力。语法结构为：
IRR(values, [guess])
内部收益率的计算公式为：
       现金流金额values不必完全相同，但现金流必须定期（比如每月或每年等）出现。该参数至少有一个正值和一个负值，否则返回错误值#NUM！。现金流数值，要按实际发生的时间顺序排列。
       函数返回结果的应用：如果现在的折现率低于IRR计算的结果，那么值得投资，反之则不可行。
示例：
       以上一节中投资设备的数据来计算投资的内部收益率。如下图所示，在B26单元格输入公式“IRR(B18:B23)”计算内部收益率，返回结果为12.01%。表明目前折现率低于12.01%时该设备是值得投资的，当高于12.01%时是不值得投资的。比如：假设折现率为12.05%，这是计算出的净现值NPV就为负数了，显然不值得投资了。
