Recall the IEEE Std 754 binary32 and binary64 formats we looked at in class. We can postulate a similar albeit smaller binary 18 floating point mmber format. Let us suppose that binary 16 has a sign bit, a 6-bit biased exponent (bias = 9-1-1-31), and 9-bit mantissa with an implied lending 1 bit. m 9 bits 1 6 bits (*) (5 pts) Show the binary16 hex representation for the floating point value - -7.125 (b) (3 pts.) Show the floating point value for the binary 18 hex representation OxC2A0
