European option pricing with the Black-Scholes-Merton model
European option pricing with the Black-Scholes-Merton model: exact price for calls and puts plus delta, gamma, theta, vega and rho, with dividend yield support. Deterministic closed-form math — the numbers agents should quote instead of hallucinating option values. Use this when an agent needs to black-Scholes price + all five Greeks.
