[Mp4-tech] [Audio] SBR Audio and noise floor decoding

In section 4.6.18.3.4 "SBR Audio and noise floor decoding" (p 216 of 
14496-3:2005) For the case where r(l) = 0 and g(l) =1 it says "i(k) is 
defined by f_TableLow(i(k)) <= f_TableHigh(k) < f_TableLow(i(k)+1))"
Is my interpretation that this i(k) function is the inverse of the 
(first) i(k) function found in 4.6.18.3.2.2, which would be INT((k+1)/2)?
Thanks,
Alex Converse
