пренебрежимо малая величина; дословно сигнал, теряющийся в шуме; за пределами точности измерения Синоним(ы): lost in the underflow
Synonym lost in the underflow. This term is from signal processing, where signals of very small amplitude cannot be separated from low-intensity noise in the system. Though popular among hackers, it is not confined to hackerdom; physicists, engineers, astronomers, and statisticians all use it.
