Another button opens a valve to deflate the BCD and decrease the volume of the equipment and causes the diver to lose buoyancy. Source: Internet
Application The BIOS in many personal computers stores the date and time in BCD because the MC6818 real-time clock chip used in the original IBM PC AT motherboard provided the time encoded in BCD. Source: Internet
As a result, this system allows for, a 32-bit packed BCD numbers to range from -50,000,000 to 49,999,999, and -1 is represented as 99999999. Source: Internet
A variable length Packed BCD numeric data type is also implemented, providing machine instructions that perform arithmetic directly on packed decimal data. Source: Internet
BCD extended existing simple four-bit numeric encoding to include alphabetic and special characters, mapping it easily to punch-card encoding which was already in widespread use. Source: Internet
