Puis b5b4b3b2b1=b50000 + b4000 + b300 + b20+b1
, 1、10、100、1000和10000
。从1到31的十进制数最多用五个二进制数就可以表示,如图3-2a所示。假设它是b5b4b3b2b1
,那么b5b4b3b2b1=b50000 + b4000 + b300 + b20+b1
,1+10+10000=10011
或者十进制数1+2+16=19
。1+10+100+1000+10000=11111
,或是十进制数1+2+4+8+16=31
1+10+10000=10011
ou nombre décimal1+2 + 16=19
. 🎜🎜Le nombre binaire du nombre 31 est 11111, il apparaîtra donc dans l'ensemble 1, l'ensemble 2, l'ensemble 3, l'ensemble 4 et l'ensemble 5. 🎜C'est un nombre binaire🎜1+10+100+1000+10000=11111
🎜, ou nombre décimal🎜1+2+4+8+16=31
