Hi Walter, Wow. I don't think I ever got a RQuantLib bug report.

Yes, looking at QuantLib's code, the file test-suite/digitaloption.cpp has DigitalOptionData values[] = { // "Option pricing formulas", E.G. Haug, McGraw-Hill 1998 - pag 88 // type, strike, spot, q, r, t, vol, value, tol { Option::Put, 80.00, 100.0, 0.06, 0.06, 0.75, 0.35, 2.6710, 1e-4 } }; Now, you sent in > library(RQuantLib) > BinaryOption("cash", "put", "european", underlying = 100, dividendYield = 0, > riskFreeRate = 0.06, maturity = 0.75, strike=80, volatility=0.35, cashPayoff > = 10) Concise summary of valuation for BinaryOption value delta gamma vega theta rho divRho 2.2155 -0.0962 0.0033 8.6306 -1.3038 -8.8749 7.2132 > but the problem is that you have q=0 (div.yeild of zero) which the quotes Huag example does not.

So ... no bug as best as I can tell. Thanks for your interest in RQuantLib. I appreciate the testing. If you are interested in contributing more unit tests, I would welcome that and can show you how to contribute.
