What is the 16-bit binary representation (in hexadecimal using lower-case letters, e.g., 0x39ab) of -13 1/4 (base 10) when represented as an IEEE 16-bit floating-point number? The IEEE 16-bit floating-point representation uses formulae consistent with those for the 32bit single-precision representation, except for using 5 bits for the exponent (instead of 8 in the case of the 32-bit representation) and a bias of 15.

Concern the following 16-bit floating point representation: The first bit is the sign of the number (0 = +, 1 = -), the next nine bits are the mantissa, the next bit is the sign of the exponent, and the last five bits are the magnitude of the exponent. All numbers are normalized, i.e. the first bit of the mantissa is one, except for zero which is all zeros. 1. How many significant binary digits do numbers in this representation...
