let\'s translate to decimal like this:
1∙81+3∙80+3∙8-1+1∙8-2+2∙8-3+5∙8-4 = 1∙8+3∙1+3∙0.125+1∙0.015625+2∙0.001953125+5∙0.000244140625 = 8+3+0.375+0.015625+0.00390625+0.001220703125 = 11.39575195312510
got It: 13.31258 =11.39575195312510
let\'s translate from decimal to binary decimal (BCD) like this:
11.39575195312510 = 1 1. 3 9 5 7 5 1 9 5 3 1 2 5 = 1(=0001) 1(=0001). 3(=0011) 9(=1001) 5(=0101) 7(=0111) 5(=0101) 1(=0001) 9(=1001) 5(=0101) 3(=0011) 1(=0001) 2(=0010) 5(=0101) = 10001.001110010101011101010001100101010011000100100101BCD
