Sistem Bilangan Desimal

Sistem Bilangan Desimal -Mungkin sudah sedikit orang yang tidak mengenal bilangan Decimal.
Desimal sendiri adalah bilangan bebasis 10, yaitu 0, 1, 2, 3, 4, 5, 6, 7, 8, dan 9.
Sistem Bilangan Desimal
Desimal sering juga disingkat dengan dec.
Bilangan ini adalah bilangan yang paling mudah digunakan manusia dan Angkanya merupakan hasil pengembangan dari Angka Arab.

 Ghiyath al-Din Jamshid Mas’ud al-Kashani Bilangan desimal diciptakan oleh Ghiyath al-Din Jamshid Mas’ud al-Kashani atau Al-Kashi.
Jamshid al-Kashi merupakan salah seorang matematikus masyhur di dunia Islam. Ia adalah seorang saintis yang mengembangkan matematika dan astronomi pada zaman kejayaan Dinasti Timurid, di Samarkand abad ke-14 M. Ia berjasa mengembangkan ilmu matematika dan astronomi dengan sederet penemuannya.

Pecahan desimal yang digunakan oleh orang-orang Cina pada zaman kuno selama berabad-abad, sebenarnya merupakan pecahan desimal yang diciptakan oleh al-Kashi. Pecahan desimal ini merupakan salah satu karya besarnya yang memudahkan untuk menghitung aritmatika yang dia bahas dalam karyanya yang berjudul Kunci Aritmatika yang diterbitkan pada awal abad ke-15 di Samarkand.

Ciri sistem bilangan desimal adalah adanya tambahan subskrip dec atau 10.
Contoh: 123dec = 12310.

25510 merupakan nilai maksimal berbentuk desimal yang dapat tersimpan dalam 1 byte.

Desimal sangat digunakan dalam kehidupan sehari-hari terutama untuk menghitung.
Dalam komputer, bilangan desimal juga dapat digunakan menjadi kode warna bernama DECIMAL RGB.
Decimal RGB Code
cara pengunaanya dalam pemograman biasanya: rgb (R,G,B) . yang R, G, dan B merupakan angka
Mengubah DECIMAL RGB kedalam HEX HTML.
Cara untuk mengubah DECIMAL RGB kedalam HEX HTML caranya cukup rumit.
Digunakan rumus RGB = (R*65536)+(G*256)+B , (dimana R adalah Merah(RED), G adalah Hijau(GREEN) dan B adalah Biru(BLUE)).
Setelah itu harus dilakukan operasi modulus pembagian 16 hingga hasil tidak dapat dibagi 16 lagi.(Disarankan pake kalkulator, tapi kalo mau manual greget mode tuh)
Contohnya:
DECIMAL RGB Code TO HEX HTML
Tabel Desimal, Biner, Oktal, Heksadesimal, dan HTML. Sampai nilai maksimal 1 byte:
