This transfer is possible in two ways: direct transfer and using the decimal system.
first, let\'s make a direct transfer.
Fill in the number with missing zeros on the left
Fill in the number with missing zeros on the right
let\'s make a direct translation from binary to postbinary like this:
001101101110.110010_{2} = 001 101 101 110. 110 010 = 001_{(=1)} 101_{(=5)} 101_{(=5)} 110_{(=6)}. 110_{(=6)} 010_{(=2)} = 1556.62_{8}
answer: 1101101110.11001_{2} = 1556.62_{8}
now let\'s make the transfer using the decimal system.
let\'s translate to decimal like this:
0∙2^{11}+0∙2^{10}+1∙2^{9}+1∙2^{8}+0∙2^{7}+1∙2^{6}+1∙2^{5}+0∙2^{4}+1∙2^{3}+1∙2^{2}+1∙2^{1}+0∙2^{0}+1∙2^{1}+1∙2^{2}+0∙2^{3}+0∙2^{4}+1∙2^{5}+0∙2^{6} = 0∙2048+0∙1024+1∙512+1∙256+0∙128+1∙64+1∙32+0∙16+1∙8+1∙4+1∙2+0∙1+1∙0.5+1∙0.25+0∙0.125+0∙0.0625+1∙0.03125+0∙0.015625 = 0+0+512+256+0+64+32+0+8+4+2+0+0.5+0.25+0+0+0.03125+0 = 878.78125_{10}
got It: 001101101110.110010_{2} =878.78125_{10}
Translate the number 878.78125_{10} в octal like this:
the Integer part of the number is divided by the base of the new number system:
878  8    
872  109  8   
6  104  13  8  
 5  8  1  
  5   

the Fractional part of the number is multiplied by the base of the new number system:

0.  78125*8 
6  .25*8 
2  .0*8 
the result of the conversion was:
878.78125_{10} = 1556.62_{8}
answer: 1101101110.11001_{2} = 1556.62_{8}
