The ieee-754 half-precision float-point format uses 16 bits: 1 sign bit, 5 bits for the exponent (biased by 15), and 10 bits for the mantissa (with a hidden bit). if the exponent is ^2, then the number is a nan or ±[infinity]
what is machine-€ for a "half-float" and the largest representable number?
