<p class=p2> 返回一个 Double，指定根据一系列定期的现金流（支付和收入）和贴现率而定的投资净现值。</p>
<p class=p2> rate 必要。Double 指定在一期间内的贴现率，用十进制表示。<br>
values() 必要。Double 数组 指定现金流值。此数组至少要包含一个负值（支付）和一个正值（收入）。</p>
<p class=p2> 说明：资的净现值是未来一系列支付或收入的当前价值。 NPV 函数使用数组中数值的顺序来解释支付和收入的顺序。要确保支付和收入值是用正确的顺序输入的。
NPV 投资在第一笔现金流值之前开始计算周期，而结束于数组中最后的现金流值。 净现值是根据未来的现金流进行计算的。如果第一笔现金流在第一期开始时发生，那么
NPV 返回的值必须加上第一笔值才是净现值。而且 values() 数组不可包含第一笔值。 NPV 函数与 PV 函数（现值）相似，只是
PV 函数在一个期间的开始或结束时才允许有现金流。与可变的 NPV 现金流值不同， PV 的现金流在整个投资期间必须固定。 </p>
