binary numbers

Numbers stored in pure binary form. Within one byte (8 bits), the values 0 to 255 can be held. Two contiguous bytes (16 bits) hold values from 0 to 65,535. See numbers and binary values.




Binary and Binary Coded Decimal
The decimal number "260" takes up only two bytes in binary rather than three bytes in binary coded decimal (BCD). The two-byte binary example above can hold a number as high as 65,535, rather than five in BCD. Binary numbers are also processed faster than BCD.






How Numbers Are Stored
Binary is one of four primary ways numbers are stored in the computer.
