let\'s translate to decimal like this:
1∙210+0∙29+0∙28+1∙27+0∙26+1∙25+1∙24+0∙23+1∙22+1∙21+1∙20+0∙2-1+1∙2-2+0∙2-3+1∙2-4+1∙2-5 = 1∙1024+0∙512+0∙256+1∙128+0∙64+1∙32+1∙16+0∙8+1∙4+1∙2+1∙1+0∙0.5+1∙0.25+0∙0.125+1∙0.0625+1∙0.03125 = 1024+0+0+128+0+32+16+0+4+2+1+0+0.25+0+0.0625+0.03125 = 1207.3437510
got It: 10010110111.010112 =1207.3437510
