PV(rate, nper, pmt[, fv[, type]])

返回一个 Double 指定在未来定期、定额支付且利率固定的年金现值。

rate 必要。Double 指定每一期的利率。例如,如果有一笔贷款年百分比率 (APR) 为百分之十且按月付款的汽车贷款,则每一期的利率为 0.1/12 或 0.0083。

nper 必要。Integer 指定一笔年金的付款总期数。例如,如果对一笔为期四年的汽车贷款选择按月付款,则贷款共有 4 * 12(或 48)个付款期。

pmt 必要。Double 指定每一期的付款金额。付款金额通常包含本金和利息,且此付款金额在年金的有效期间不变。

fv 可选。Variant,指定在付清贷款后所希望的未来值或现金结存。例如,贷款的未来值在贷款付清后为 0 美元。但是,如果想要在 18 年间存下 50,000 美元作为子女教育基金,那么 50,000 美元为未来值。如果省略的话,缺省值为 0。

type 可选。Variant 指定贷款到期时间。如果贷款是在贷款周期结束时到期,则请使用 0。如果贷款是在周期开始时到期,则请使用 1。如果省略的话,缺省值为 0。

说明:年金是在一段时间内一系列固定现金支付。年金可以是贷款(如房屋抵押贷款),也可以是一笔投资(如按月储蓄计划)。 在支付期间必须用相同的单位计算 rate 和 nper 参数。例如,如果 rate 用月份计算,则 nper 也必须用月份计算。 对所有参数,现金支出(如储蓄存款)用负数表示,而现金收入(如红利支票)用正数表示。

Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.
