Homework #2

Due Monday September 29^th by 4:45 pm

• Complete the following table:

Fractional form	Binary	Decimal
5/6
	1010.010
		2.2

• Convert 0.6 to IEEE single precision format.
• Convert BEEF0000h from IEEE single precision floating point format to a decimal number.
• The number 4,000,000 can be represented exactly in IEEE single precision format. What is the next largest floating point value that can be represented exactly in IEEE single precision format? Give both its decimal value and it’s IEEE representation.
• What are the largest and smallest values IEEE single precision format can represent? (Hint – there is really only one question here!) You must show the IEEE format for the number, and write the base 2 scientific notation for the number, but you don’t need to figure out its decimal value.
• Write C (or C++) code to change the sign of a floating point number without using arithmetic. Use only bitwise operations. (This is a one liner!)
