Hello, I received a question whereby I had to convert to fractional decimals to binary.
0.28125 and 0,65625
Using the methods taught me to convert them to fractional binary I got .01001 and .10101 respectively.
Next we were required to add the two binary fractions, which my answer was: .11110
Then we were asked to convert this binary fraction decimal. This I do not know how to do. Can anyone please tell me how to do this if they know?
Thanks

You figured out the hard way, and now you're having trouble with the easy way?

Answer #1: cheat! :)
#! /bin/bash
bin1=".01001"
dec1=`echo -e "ibase=2\n e(l(${bin1}))" | bc -l`
bin2=".10101"
dec2=`echo -e "ibase=2\n e(l(${bin2}))" | bc -l`
bin3=".11110"
dec3=`echo -e "ibase=2\n e(l(${bin3}))" | bc -l`
echo "$bin1 => $dec1"
echo "$bin2 => $dec2"
echo "$bin3 => $dec3"Answer #2: not really an answer, but might provide a clue or two.
