The floating point representation of a number has two parts. The first parts represent a signed, fixed- point number called the mantissa. The second part designates the position of the decimal point and is called the exponent. The fixed-point mantissa may be a fraction or an integer. For example, the decimal number +6132.789 is represented in floating-point with a fraction and an exponent as follows:
Fraction Exponent
+0.6132789 +04
This representation is equivalent to the scientific notation +0.6132789*10^+4.
Floating –point is always interpreted to represent a number in the following form:
M*r ^e
Only the mantissa m and the exponent e are physically represented in
