Some programming languages (or compilers for them) provide a built-in (primitive) or library decimal data type to represent non-repeating decimal fractions like 0.3 and −1.17 without rounding, and to do arithmetic on them.
The indicators are used to create a health index, an education index and an income index, each with a value between 0 and 1. The geometric mean of the three indices—that is, the cube root of the product of the indices—is the human development index. A value above 0.800 is classified as very high, between 0.700 and 0.799 as high, 0.550 to 0. ...
There are challenges in comparing life expectancies across countries due to disparities in data reporting and collection standards. The primary source of the most recent data presented is the World Bank Group's 2022 report.
Income ratios include the pre-tax national income share held by top 10% of the population and the ratio of the upper bound value of the ninth decile (i.e. the 10% of people with highest income) to that of the upper bound value of the first decile (the ratio of the average income of the richest 10% to the poorest 10%).
The current world population growth is approximately 1.09%. [7] People under 15 years of age made up over a quarter of the world population (25.18%), and people age 65 and over made up nearly ten percent (9.69%) in 2021. [7] The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999.
The Han Chinese are the world's largest single ethnic group, constituting over 19% of the global population in 2011. [82] The world's most-spoken languages [a] are English (1.132B), Mandarin Chinese (1.117B), Hindi (615M), Spanish (534M) and French (280M). More than three billion people speak an Indo-European language, which is the largest ...
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.
[161] [162] The publication has global coverage and tracks whether the world is making progress towards the SDGs. [163] It aims to make the data on the 17 goals available and understandable to a wide audience. [164] The SDG-Tracker highlights that the world is currently (early 2019) very far away from achieving the goals.
