   a) The input of decimal number is:
   b) After conversion, the 1-bit sign bit is:
   c) The8-bitactualexponentis:
   d) The 8-bit biased exponent is:
   e) The 23-bit fraction is:
   f) IEEE754 binary floating point:

2. Ask users to type in a 32-bits binary number in IEEE754 binary floating point format (single precision) from the keyboard input, then convert this IEEE 754 binary floating point number (single precision) into the decimal number format.
