Changes since v5
- Switch fixpoint scaling from decimal with a factor 100 to binary with 
  a shift of 7 bits to increase accuracy. In v5 decimal scaling was used 
  since it closest resembled the v4 implementation of a decimal scaling 
  with 1000 as a factor. The big change in v5 was to fit all  
  calculations inside a int instead of s64.

Pity, I couldn't test it on HW before leaving for christmas. Will
definately do when I come back!

Thanks for this update!
