The number has two parts.
- Integer Part
- Fraction Part
Integers are numbers without the fraction part.
They can range from negative infinity to positive infinity.
Integers are further divided into two parts.
- Unsigned number (0 to (2^n – 1); here n = width of data bus)
- Signed Numbers ((-2^(n-1)) to (2^n – 1))
Fractional numbers or Floating Point numbers are stored in a standard format known as IEEE 754.
IEEE 754 Floating-Point Standard comes in three different modes.
- Single precision Format (32 bits)
- Double-precision format
