ieee-754 to decimal conversion

here decimal means the equivalent real value...........

what i want to do is ............

simply to convert a 32 bit binary(ieee-754) to its equivalent float(real value)...........it is obvious that an ieee-754-binary is represented as

1st bit as sign

next 8 bits for exponent

and the rest 23 bits for mantisa or fraction part........

and equivalnt is a float value(eg:7.35)
