4. NOTE: there is a continuation sheet for this problem. DO NOT Crom everything on this sheet. Recall the IEEE Std 754 binary32 and binary64 formats we looked at in class. We can postulate a similar albeit smaller binary 16 floating-point mumber format. Let us suppose that binary 18 has a sign bit, a 6-bit biased exponent (bins 26-1-1=31), and a 9-bit mantissa with an implied leading 1 bit. m 5 1 6 bits+ 9 bits (a) (5 pts.) Show the binary 16 hex representation for the floating point value - -7.125 (b) (5 pts.) Show the floating point value for the binary16 hex representation OxC2A0
