1 sign and 3 exponent bits. AFAIK at the small number of bits it’s basically a teeny tiny look up table so you can precompute the table to be whatever math you want. Having an exponent instead of mantissa just means that the values that can be expressed are not linearly separated.

Being expressed as 1 10 100 1000 is not really different than being expressed as 1 2 3 4. There's still only four bits, i.e. 16 different possible values, no matter how we decide to express that in human-friendly terms.
