| A calculating machine having a 10-digit keyboard is provided with a register for temporarily storing values and is selectively engageable with the actuating mechanism to receive values therefrom. A function lever is operatively connected to the register through a linkage which laterally displaces the register in response to positioning of the function lever to cancel decimal positions. The frame of the register is also provided with a lever which is engageable with the actuating mechanism for rounding off the decimal value before the cancelled positions.

| 13 | Decimal to binary encoder for generating decimal point position and round-off information in a calculator | US3685041D | 1970-05-12 | US3685041A | 1972-08-15 | KONDUR NICHOLAS JR |
| A decimal to binary encoder for generating both decimal point position and round-off information for instructing calculator memory register or printout logic. The encoder includes two sets of permanent magnets and associated reed switches, each switch having a binary value. An individual coded shunt plate containing variously shaped apertures is interposed between each set of magnets and its switches for permitting patterns of magnetic fields through the plate, thereby closing different combinations of switches depending on the position of each plate with respect to its set of magnets and switches. The positioning of the decimal point location shunt plate also positions the round-off shunt plate so that round-off is always made with respect to the decimal point location. The round-off setting is effected by positioning the round-off set of magnets and switches in relation to the previously positioned round-off shunt plate.
