III_requantize question

Hi!

I am working with mad-0.15.0
I hope someone may give me answer on this questions:

1. The result of this function III_exponents() in layer3.c file is
   signed int exponents[39] array. My question - in which format
   is result presented?

2.
      Xr = is^(4/3) * 2^(exp)       (sign not discussed)

      What value exp can be and what step?
      -88.5 <= exp <= 11.5, 0 <= is[i] <= 8207
      are this equation true?

      From III_requantize() it is look like step is 2^(1/4) - where can I take this
      information?

Thank for Your answers.
