A decimal separator is a symbol that separates the integer part from the fractional part of a number written in decimal form. Different countries officially designate different symbols for use as the separator. The choice of symbol can also affect the choice of symbol for the thousands separator used in digit grouping.
In the example below, the divisor is 101 2, or 5 in decimal, while the dividend is 11011 2, or 27 in decimal. The procedure is the same as that of decimal long division; here, the divisor 101 2 goes into the first three digits 110 2 of the dividend one time, so a "1" is written on the top line. This result is multiplied by the divisor, and ...
In some systems, while the base is a positive integer, negative digits are allowed. Non-adjacent form is a particular system where the base is b = 2.In the balanced ternary system, the base is b = 3, and the numerals have the values −1, 0 and +1 (rather than 0, 1 and 2 as in the standard ternary system, or 1, 2 and 3 as in the bijective ternary system).
Densely packed decimal (DPD) is an efficient method for binary encoding decimal digits.. The traditional system of binary encoding for decimal digits, known as binary-coded decimal (BCD), uses four bits to encode each digit, resulting in significant wastage of binary data bandwidth (since four bits can store 16 states and are being used to store only 10), even when using packed BCD.
The label for columns contains the second decimal place of Z. The values within the table are the probabilities corresponding to the table type. These probabilities are calculations of the area under the normal curve from the starting point (0 for cumulative from mean , negative infinity for cumulative and positive infinity for complementary ...
7 = 111 2, 13 = 111 3, 31 = 11111 2 = 111 5, 43 = 111 6, 73 = 111 8, 127 = 1111111 2, 157 = 111 12, ... (sequence A085104 in the OEIS ) While the sum of the reciprocals of the prime numbers is a divergent series, the sum of the reciprocals of the Brazilian prime numbers is a convergent series whose value, called the "Brazilian primes constant ...

Liu Hui expressed mathematical results in the form of decimal fractions that utilized metrological units (i.e., related units of length with base 10 such as 1 chǐ = 10 cùn, 1 cùn = 10 fēn, 1 fēn = 10 lí, etc.); this led Liu Hui to express a diameter of 1.355 feet as 1 chǐ, 3 cùn, 5 fēn, 5 lí. [4]
