14 has an aliquot sum of 8, within an aliquot sequence of two composite numbers (14, 8, 7, 1, 0) in the prime 7-aliquot tree. 14 is the third companion Pell number and the fourth Catalan number . [ 2 ] [ 3 ] It is the lowest even n {\displaystyle n} for which the Euler totient φ ( x ) = n {\displaystyle \varphi (x)=n} has no solution, making ...
Decimals may sometimes be identified by a decimal separator (usually "." or "," as in 25.9703 or 3,1415). [3] Decimal may also refer specifically to the digits after the decimal separator, such as in "3.14 is the approximation of π to two decimals". Zero-digits after a decimal separator serve the purpose of signifying the precision of a value.
As an example, a 4-byte value consists of 8 nibbles, wherein the upper 7 nibbles store the digits of a 7-digit decimal value, and the lowest nibble indicates the sign of the decimal integer value. Standard sign values are 1100 ( hex C) for positive (+) and 1101 (D) for negative (−).
[3] [4] E.g., the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7 but the integers 2 and 3 are not because each can only be divided by one and itself. The composite numbers up to 150 are:
Arabic numerals on a 14-segment display. By lighting different elements, different characters can be displayed. In a 14-segment display, there is also an optional 15th segment which is a decimal point (denoted as "DP").
European languages that use the comma as a decimal separator may correspondingly use the period as a thousands separator. As a result, some style guides [example needed] recommend avoidance of the comma (,) as either separator and the use of the period (.) only as a decimal point. Thus one-half would be written 0.5 in decimal, base ten notation ...
the 4 to the right of the tenths place is in the hundredths place, and is called the hundredths digit. [10] The total value of the number is 1 ten, 0 ones, 3 tenths, and 4 hundredths. The zero, which contributes no value to the number, indicates that the 1 is in the tens place rather than the ones place.
Also the converse is true: The decimal expansion of a rational number is either finite, or endlessly repeating. Finite decimal representations can also be seen as a special case of infinite repeating decimal representations. For example, 36 ⁄ 25 = 1.44 = 1.4400000...; the endlessly repeated sequence is the one-digit sequence "0".
