DEVICE FOR COMPUTING FUNCTIONS Russian patent published in 1994 - IPC

Abstract SU 1755650 A1

FIELD: computer technology. SUBSTANCE: trigonometrical, hyperbolic, logarithmic, power, exponential functions may be computed. Algorithm is used in the device based upon multiplicative approach to presentation of quantity, which permits to reduce number of operations. High speed of operation is achieved due to analyzing two digits of operand. EFFECT: widened range of problems to be solved. 4 cl, 26 dwg
