"Binary Data Representation"
- A binary number may also have a binary point, in addition to the sign.
- The binary point is used for representing fractions, integers and integer-fraction numbers.
- Registers are high-speed storage areas within the Central Processing Unit (CPU) of the computer.
- All data are brought into a register before it can be processed. For example, if two numbers are to be added, both the numbers are brought in registers, added, and the result is also placed in a register.
Two ways of representing the position of the binary point in the register:
- There are two ways of representing the position of the binary point in the register:
- fixed point number representation and
- floating point number representation.
- The fixed point number representation assumes that the binary point is fixed at one position either at the extreme left to make the number a fraction, or at the extreme right to make the number an integer. In both cases, the binary point is not stored in the register, but the number is treated as a fraction or integer.
- For example, if the binary point is assumed to be at extreme left, the number 1100 is actually treated as 0.1100.
