In floating point representation of +6132.789 exponent is
In floating point representation of +6132.789 exponent is +04.
The floating-point representation of a number has two parts. The first part represents a signed, fixed-point number called the mantissa. The second part designates the position of the decimal (or binary) point and is called the exponent. The fixed-point mantissa may be a fraction or an integer.
The value of the exponent indicates that the actual position of the decimal point is four positions to the right of the indicated decimal point in the fraction. This representation is equivalent to the scientific notation +0.6132789 X 10+4.
Floating point numbers has a single digit to the left of the decimal point. Computer arithmetic that supports such numbers is called floating point.
