Various BCD implementations exist that employ other representations for numbers. Programmable calculators manufactured by Texas Instruments, Hewlett-Packard, and others typically employ a floating-point BCD format, typically with two or three digits for the (decimal) exponent. The extra bits of the sign digit may be used to indicate special numeric values, such as infinity, underflow/overflow, and error (a blinking display). WebWho created the BCD code? The BCD code (6-bit) (Binary Coded Decimal) is a code 6-bit standard used by mainframe computers: Borroughs, Bull, CDC, IBM, General Electric, NCR, Siemens, Sperry-Univac, etc… IBM I think a code for punch cards from the 1960s that spread among other manufacturers.
