The base-2 representation of the expected value is 111000100010001100011000000000000000000 and that of the actual value is 111100100010001100011000000000000000000 There's a single bit of difference. -- Álvaro Herrera Valdivia, Chile "No hay hombre que no aspire a la plenitud, es decir, la suma de experiencias de que un hombre es capaz"
