BILANGAN KOMPLEMEN

• Pengurangan Bilangan Dengan Komplemen
Metode pengurangan binary biasa dilakukan oleh manusia, untuk komputer biasanya menggunakan metode komplemen (complement) yaitu :
– Komplemen basis min – 1 ( Radix minus one complement )
– Komplemen basis ( Radix )
Komplemen pada dasarnya merubah bentuk pengurangan menjadi bentuk pertambahan.
Dalam sistem desimal, ada 2 macam komplemen yaitu :
– Komplemen 9 ( 9’s complement )
– Komplemen 10 ( 10’s complement )
Dalam sistem biner :
– Komplemen 1 ( 1’s complement )
– Komplemen 2 ( 2’s complement )
• Komplemen 9 ( 9’s Complement )
Komplemen 9 dari suatu bilangan desimal delakukan dengan cara mengurangkan angka 9 untuk masing – masing digit dalam bilangan pengurang.
Contoh :
Komplemen 9 dari 24 adalah 75, yaitu : 99 – 24 = 75
Komplemen 9 dari 321 adalah 678, yaitu : 999 – 321 = 678
Pengurangan biasa Komplemen 9 Dalam komplemen 9 digit yang paling
859859 kiri ditambahkan pada digit paling kanan.
523 _ 476 +336 13351 +336
• Komplemen 10 ( 10’s Complement )
Komplemen 10 dari suatu bilangan dilakukan dengan cara, hasil komplemen 9 ditambah 1 ( cari komplemen 9 lalu ditambah 1 ).
• Komplemen 1 ( 1’s Complement )
Komplemen 1 dari suatu bilangan biner dilakukan dengan cara mengurangkan semua digit dengan nilai bit 1/ merubah bit ‘0’ menjadi ‘1’ atau bit ‘1’ menjadi ‘0’.
Dalam komplemen 1, digit 1 paling ujung kiri ditambahkan pada digit paling kanan.
• Komplemen 2 ( 2’s Complement )
Komplemen 2 dari suatu bilangan biner dilakukan dengan cara, hasil komplemen 1 ditambah 1.
Komplemen 2 dari bilangan biner 1011010110
• Komplemen 7 ( 7’s Complement )
Komplemen 7 dari suatu bilangan oktal dilakukan dengan cara, mengurangkan angka 7 untuk masing – masing digit dalam bilangan pengurangan.
• Komplemen 8 ( 8’s Complement )
Komplemen 8 dari suatu bilangan dilakukan dengan cara, hasil komplemen 7 ditambah 1 (cari komplemen 7 dulu lalu ditambah 1).
• Komplemen 15 ( 15’s Complement )
Komplemen 15 dari suatu bilangan hexadesimal dilakukan dengan cara, mengurangkan angka 15 untuk masing – masing digit dalam bilangan pengurangan.
• Komplemen 16 ( 16’s Complement )
Komplemen 16 dari suatu bilangan dilakukan dengan cara, hasil komplemen 15 ditambah 1 (cari komplemen 15 dulu lalu ditambah 1).

One small reason why we should all learn to choose wood

One of the biggest threats to our children’s future is climate change caused by global warming.
There is no single, simple solution, but we’d like to tell you about the good wood can do and why all of us should, wherever possible, be using it.
Trees suck in carbon dioxide out of the air and lock it away, so forestry is a vital part of any strategy to slow global warming. When we use the wood, the carbon stays locked up and the replanted trees start the cycle again.
And, despite what you might believe, Europe’s stock of trees is actually growing, as we currently plant more than two trees for every one that we cut.
Not only is wood renewable, but it takes less energy to fell, transport and process than other building materials. And because it is a natural insulator, timber frame houses use less fuel to heat.
So, next time when you need new floor, replacement with window, a patio or a new kitchen, stop or just a moment, remember all those little reason for choosing wood.
