How would one represent the number -4 as an 8-bit normalised, 2's complement, floating point, with 4 bits dedicated to the exponent?
As a normal 4-bit 2's complement number, it would be represented as 1100.
How would this be normalised, with the start of the mantissa being 1.0?
Would it be 1.000 0010, with the extra 1 on the left (after evaluation to a normal 2's compliment number) being filled in?
If so, how would you know to fill it with a 1, because it starts with a 1?
