Number of 6's between 1 to 18000
Is there a smart way to solve this..?
I can see a brute force type of way.... by looking at the number of 6's from 1-100, then 101 to 200 etc... and special cases for 601-700 etc... but it seems very long, tedius and prone to error?
Thanks for any ideas.

Fast Multiplication of Normalized 16 bit Numbers with SSE2
If you are compositing pixels with 16 bits per component, you often need this computation:

r = (a * b + 0x7fff) / 65535;
There is a well-known way to do this quickly without a division:
