In the decimal system, for example, there is 0. 9 = 1. 0 = 1; in the balanced ternary system there is 0. 1 = 1. T = 1 / 2 . A rational number has an indefinitely repeating sequence of finite length l , if the reduced fraction's denominator contains a prime factor that is not a factor of the base.
An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered). [1]
A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented ...
Stylistic impression of the repeating decimal 0.9999..., representing the digit 9 repeating infinitely In mathematics , 0.999... (also written as 0. 9 , 0. . 9 , or 0.(9) ) is a repeating decimal that is an alternative way of writing the number 1 .
Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal to zero. Thus a non-negative number is either zero or positive.
Therefore, the result is a fraction with an odd numerator and an even denominator, which cannot be an integer. [17] More generally, any sequence of consecutive integers has a unique member divisible by a greater power of two than all the other sequence members, from which it follows by the same argument that no two harmonic numbers differ by an ...

However, in case of negative numbers, there are various conflicting ways to extend the fractional part function to them: It is either defined in the same way as for positive numbers, i.e., by = ⌊ ⌋ (Graham, Knuth & Patashnik 1992), [6] or as the part of the number to the right of the radix point = | | ⌊ | | ⌋ (Daintith 2004), [7] or by the odd function: [8]
