irFixedFloatingSwapPricer
语法
irFixedFloatingSwapPricer(instrument, pricingDate,
discountCurve, forwardCurve, assetPriceCurve, [setting])
详情
计算固定利率互换（IR Fixied-Floating Swap, IRS）的定价。
返回值：
-
当 setting 设置 calcCashFlow 时返回一个字典。
-
否则，返回一个 DOUBLE 标量。
参数
instrument INSTRUMENT 类型标量，一个 IrFixedFloatingSwap 对象，表示需要定价的固定利率互换。
pricingDate DATE 类型标量，表示定价日期。
discountCurve MKTDATA 类型标量，一个 IrYieldCurve 对象，表示用于计算折现因子的即期曲线。
forwardCurve MKTDATA 类型标量，一个 IrYieldCurve 对象，表示用于计算远期利率的即期曲线。
assetPriceCurve MKTDATA 类型标量，一个 AssetPriceCurve 对象，用于传入利率互换浮动端参考利率的历史数据。
setting 可选参数，一个键为 STRING 类型，值为 ANY 类型的字典，用于指定计算设置，支持的键值对包括：
| key | value | 说明 |
|---|---|---|
| calcCashFlow | BOOL | 是否计算现金流 |
例子
例1. 以 FR_007 为参考利率的利率互换定价。
