I am reviewing floating point topic( in the photo) This is largest number in 32bits machine, I know the yellow circle, but i am confusing about the green one. Can you give me the general formula and then replace it by the number , so that i can understand. One more thing, Can you show me to do the same ( largest number ) in machine 12 bits. Please shown me as details as you can. i really need the details solution now. Thanks
