  1. Bilangan pecahan By: Moch. Rif’an

  2. Dengan : (A)r = Bilangan A1 = Digit ke 1 di belakang koma A2 = Digit ke 2 di belakang koma A3 = Digit ke 3 di belakang koma An = Digit ke n di belakang koma r = radik

  3. 1.6.1 Bilangan pecahan Biner Contoh: (0,10011) 2 = (………)10 Solusi:

  4. Contoh: (0,59375)10 = (……….)2 Solusi: 0,59375 × 2 = 1,1875 0,1875 × 2 = 0,375 0,375 × 2 = 0,75 0,75 × 2 = 1,5 0,5 × 2 = 1,0 Jadi, (0,5937)10 = (0,10011)2

  5. Bilangan pecahan Oktal Contoh: (0,71)8 = (………)10 Solusi:

  6. Contoh: (0,89025)10 = (……….)8 Solusi: 0,89025 × 8 = 7,125 0,125 × 8 = 1,0 Jadi, (0,89025)10 = (0,71)8

  7. Bilangan pecahan Heksadesimal Contoh 1.18: (0,EF1) 16 = (………)10 Solusi:

  8. Contoh: (0,933837890625)10 = (……….)16 Solusi: 0,933837890625 × 16 = 14,94140625 0,94140625 × 16 = 15,0625 0,0625 × 16 = 1,0 Jadi, (0,933837890625)10 = (0,EF1)16

  9. Kode By: Moch. Rif’an

  10. BCD (Binary Code to Desimal)

  11. Desimal 3 7 BCD 0011 0111 Sehingga (37)10 = (00110111)BCD

  12. Kode Gray

  13. Kode ASCII

  14. Kode Excess-3

  15. Kode Excess-3

  16. Post test

  17. Kita Lanjutkan Pertemuan Berikutnya
