Açıklamalar

Bir Decimal sayının ikili gösterimi 1 bit işaretinden, 96 bitlik bir tamsayıdan ve tamsayı sayısını bölmek ve hangi bölümünün ondalık kesir olduğunu belirtmek için kullanılan ölçeklendirme faktöründen oluşur. Ölçeklendirme faktörü örtük olarak 10 sayısıdır ve 0 ile 28 arasında bir üs oluşturur.

bits 32 bit imzalı tamsayılardan oluşan dört öğeli uzun bir dizidir.

bits [0], bits [1], ve bits [2] 96 bit tamsayı sayısının düşük, orta ve yüksek 32 bitini içerir.

bits [3] ölçek faktörünü ve işaretini içerir ve aşağıdaki bölümlerden oluşur:

Küçük sözcük olan 0 ile 15 arasında bitler kullanılmaz ve sıfır olmalıdır.

16 ile 23 arasındaki bitler, tamsayıyı bölmek için 10'un gücünü gösteren 0 ile 28 arasında bir üs içermelidir.

24 ile 30 arasında bitler kullanılmaz ve sıfır olmalıdır.

Bit 31 işareti içerir; 0 pozitif, 1 negatif anlamına gelir.

Sayısal bir değerin birkaç olası ikili gösterimi olabilir; tümü eşit oranda geçerli ve sayısal olarak eşdeğerdir. Bit gösteriminin negatif ve pozitif sıfır arasında ayrım olduğunu unutmayın. Bu değerler tüm işlemlerde eşit olarak kabul edilir.
