The bit calculator

If you are not involved in converting dual/decimal numbers on a daily basis, this little bit calculator may be of help: simply set the corresponding bits by clicking on them and read off the byte value. As the most significant bit is written first, we start with bit 8 (7). The bit number is followed by the significance:
Bit 8 (7) Bit 7 (6) Bit 6 (5) Bit 5 (4) Bit 4 (3) Bit 3 (2) Bit 2 (1) Bit 1 (0) Dezimal
128 64 32 16 8 4 2 1
