<div class="textblock"><p>Base inflation-coupon pricer. </p>
<p>The main reason we can't use <a class="el" href="class_quant_lib_1_1_floating_rate_coupon_pricer.html" title="generic pricer for floating-rate coupons">FloatingRateCouponPricer</a> as the base is that it takes a <a class="el" href="class_quant_lib_1_1_floating_rate_coupon.html" title="base floating-rate coupon class">FloatingRateCoupon</a> which takes an <a class="el" href="class_quant_lib_1_1_interest_rate_index.html" title="base class for interest rate indexes">InterestRateIndex</a> and we need an inflation index (these are lagged).</p>
<p>The basic inflation-specific thing that the pricer has to do is deal with different lags in the index and the option e.g. the option could look 3 months back and the index 2.</p>
<p>We add the requirement that pricers do inverseCap/Floor-lets. These are cap/floor-lets as usually defined, i.e. pay out if underlying is above/below a strike. The non-inverse (usual) versions are from a coupon point of view (a capped coupon has a maximum at the strike).</p>
<p>We add the inverse prices so that conventional caps can be priced simply. </p>
