Behavior and limits

Statistical functions convert inputs to 64-bit floating point. NaN and infinity follow Go's floating-point rules. Prime helpers handle zero, negative numbers, and large boundary values. Range functions accept their bounds in either order. Random generation and reseeding are safe across threads.
