would 19.9 in base 10 would be 0001 1001.1110 or 0001 1001.0111 in BCD?

do you start from right and continue to go left?
I believe this converts 0.9 into binary and not BCD.
I think 0.9 in BCD will simply be 0.1001 as the whole point of BCD is to use 0-9 binary representations of numbers to avoid these conversions. Forgive in advance if I am wrong. (as per Wiki. 0.2 = 0.0010)
hmm.. so your saying 8 = 1000 in BCD, i agree. so .8 must be .1000... i guess. so your saying that for BCD .x is read in whole numbers and only binary is read by 1/2+1/4+1/8 excetera?
therefore .8 = 1000 in BCD and .8 = 1100 -approximately (it is actually 7.5), is that what you mean?
and you are right about it being read as whole numbers since the purpose of BCD is to take each digit in the number and represent it in binary form using 4 bits of data.
