A repeating decimal or recurring decimal is a decimal representation of a number whose digits are eventually periodic (that is, after some place, the same sequence of digits is repeated forever); if this sequence consists only of zeros (that is if there is only a finite number of nonzero digits), the decimal is said to be terminating, and is ...
Division by zero. The reciprocal function y = 1 x. As x approaches zero from the right, y tends to positive infinity. As x approaches zero from the left, y tends to negative infinity. In mathematics, division by zero, division where the divisor (denominator) is zero, is a unique and problematic special case.
The fractional part or decimal part [1] of a non‐negative real number is the excess beyond that number's integer part. The latter is defined as the largest integer not greater than x, called floor of x or . Then, the fractional part can be formulated as a difference : For a positive number written in a conventional positional numeral system ...
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
In terms of partition, 20 / 5 means the size of each of 5 parts into which a set of size 20 is divided. For example, 20 apples divide into five groups of four apples, meaning that "twenty divided by five is equal to four". This is denoted as 20 / 5 = 4, or 20 / 5 = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is ...
4.4 Tm – 29.4 au – Perihelion distance of Pluto; 4.5 Tm – 30.1 au – Distance between Neptune and the Sun; 4.5 Tm – 30.1 au – Inner radius of the Kuiper belt; 5.7 Tm – 38.1 au – Perihelion distance of Eris; 6.0 Tm – 40.5 au – Distance from Earth at which the Pale Blue Dot photograph was taken. 7.3 Tm – 48.8 au – Aphelion ...
For example, in base 2 (the binary numeral system) 0.111... equals 1, and in base 3 (the ternary numeral system) 0.222... equals 1. In general, any terminating base expression has a counterpart with repeated trailing digits equal to − 1. Textbooks of real analysis are likely to skip the example of 0.999... and present one or both of these ...
Spectral line at 121.6 nm, 10.20 eV. Extreme ultraviolet: EUV 10–121 10.25–124, 1.642–19.867 Entirely ionizing radiation by some definitions; completely absorbed by the atmosphere. Vacuum ultraviolet VUV 10–200 6.20–124, 0.993–19.867 Strongly absorbed by atmospheric oxygen, though 150–200 nm wavelengths can propagate through nitrogen.
