In this question, we consider a non-standard floating point number representation, which is based on IEEE-754 but has different order and lengths of fields as shown below: Mantissa (15 bits) Sign (1 bit) Exponent (16 bits) Assume that the bias is still calculated based on the formula: 2exponent 1. Convert the following decimal numbers into the above non-standard representation form. Please write down all intermediate steps of the calculations of mantissa and exponent.
