Decimal to binary Conversion of (357) 10 to binary notation results in (101100101) To convert from a base-10 integer to its base-2 (binary) equivalent, the number is divided by two. The remainder is the least-significant bit. The quotient is again divided by two; its remainder becomes the next least significant bit.
As an example, encoding the decimal number 91 using unpacked BCD results in the following binary pattern of two bytes: Decimal: 9 1 Binary : 0000 1001 0000 0001 In packed BCD, the same number would fit into a single byte: Decimal: 9 1 Binary : 1001 0001
In computer science, the double dabble algorithm is used to convert binary numbers into binary-coded decimal (BCD) notation. [1] [2] It is also known as the shift-and-add -3 algorithm, and can be implemented using a small number of gates in computer hardware, but at the expense of high latency. [3]
That is, the value of an octal "10" is the same as a decimal "8", an octal "20" is a decimal "16", and so on. In a hexadecimal system, there are 16 digits, 0 through 9 followed, by convention, with A through F. That is, a hexadecimal "10" is the same as a decimal "16" and a hexadecimal "20" is the same as a decimal "32".
For example, to calculate the decimal number −6 in binary from the number 6: Step 1: +6 in decimal is 0110 in binary; the leftmost significant bit (the first 0) is the sign (just 110 in binary would be -2 in decimal). Step 2: flip all bits in 0110, giving 1001. Step 3: add the place value 1 to the flipped number 1001, giving 1010.
Binary-coded decimal. Binary-coded decimal (BCD) is a binary encoded representation of integer values that uses a 4-bit nibble to encode decimal digits. Four binary bits can encode up to 16 distinct values; but, in BCD-encoded numbers, only ten values in each nibble are legal, and encode the decimal digits zero, through nine.
Three decimal digits is equivalent to about 10 binary digits, so we should round 0.05 to 10 bits after the binary point. The closest approximation is then 0.0000110011. 10 = 8 + 2 = 2 3 + 2 1 1 = 2 0 0.5 = 2 − 1 0.05 = 0.0000110011 2 {\displaystyle {\begin{aligned}10&=8+2=2^{3}+2^{1}\\1&=2^{0}\\0.5&=2^{-1}\\0.05&=0.0000110011_{2}\end{aligned}}}
The original binary value will be preserved by converting to decimal and back again using: 5 decimal digits for binary16, 9 decimal digits for binary32, 17 decimal digits for binary64, 36 decimal digits for binary128. For other binary formats, the required number of decimal digits is
In the decimal encoding, it is encoded as a series of p decimal digits (using the densely packed decimal (DPD) encoding). This makes conversion to decimal form efficient, but requires a specialized decimal ALU to process. In the binary integer decimal (BID) encoding, it is encoded as a binary number.
