The question asks for the decimal number that 0x0C000000 represents if it is a floating number. I'm not too sure on how to approach this, but here's my thought process:
0x0C000000 = 0000 1100 0000 0000 0000 0000 0000 0000
The first digit is 0, so it's positive. The exponent is 0x0C = 12 - 127 = -116. The mantissa is 0x0C0000 = 12 * 16 ^ -2 = 0.046875, so the final answer is 1.046874 * 2 ^ -116. While my book has similar examples that I tried to follow along with, none were exactly of this type, so I highly suspect I'm doing something wrong. Any tips, hints, or strategies would be greatly appreciated.
