You must show all work in order to receive any credit for your solutions. 1. Decode the following bit pattern using the following Foating-point format: 1 sign bit, 8 bits of exponent (the bias is 127), and 23 bits of mantissa. (3 points) 1100 0010 0100 1011 0000 0000 0000 0000 Sign bit: 1 Exponent: 10000100 Mantissa: 10010110000000000000000 Exponent = 10000100 = (128 + 4) = 132 - 127 (the bias) = 5 Restored mantissa: 1.10010110000000000000000 x 2 5 Shifting the binary point back to the right, we get 110010.11000. ..
