1) Convert the decimal number into a binary number with three places to the right of the binary point.

2) Convert the binary number into a hexadecimal number.

Part II - Adding Binary Numbers

Select two decimal numbers between -60 and +60. One should be a positive number and the other should be a negative number.

Convert the numbers into 8-bit unsigned numbers with negative numbers in the 2s complement form. (Remember that positive numbers have the leftmost bit =0 and negative numbers have the leftmost bit =1). Now, Add the two numbers together to generate an eight-bit binary result. You MUST show your work completely!

Part III Do a little research and respond to the following:

If a computer is capable only of manipulating and storing integers only, what difficulties will this scenario presents? How could or are these difficulties overcome in computing?
