1. ## Hex to Octal

Base 16: 4.BF85 to binary in 4 bit patterns = 0100 1011 1111 1000 0101

In 3 bit patterns this is: 01 001 011 111 110 000 101

Which corresponds in octal to: 1137605

Where would I put the decimal point?

2. ## I solved it

I didn't think to treat the fractional part separately from the integer.
