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.

The Day of Five Billion, 11 July 1987, was designated by the United Nations Population Fund as the approximate day on which the world population reached five billion. Matej Gašpar from Zagreb , Croatia (then SR Croatia , SFR Yugoslavia ), was chosen as the symbolic 5-billionth person alive on Earth .
The number of neuronal connections in the human brain (estimated at 10 14), or 100 trillion/100 T; The Avogadro constant is the number of "elementary entities" (usually atoms or molecules) in one mole; the number of atoms in 12 grams of carbon-12 – approximately 6.022 × 10 23, or 602.2 sextillion/60.2Sx.
To represent the number 1,230,400 in normalized scientific notation, the decimal separator would be moved 6 digits to the left and × 10 6 appended, resulting in 1.2304 × 10 6. The number −0.004 0321 would have its decimal separator shifted 3 digits to the right instead of the left and yield −4.0321 × 10 −3 as a result.
The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999. [16] [17] [18] It reached the 2 billion mark in 1927, the 3 billion mark in 1960, 4 billion in 1974, and 5 billion in 1987. [19] The overall population of the world is approximately 8 billion as of November 2022.
The Day of Eight Billion, marked on 15 November 2022, was designated by the United Nations as the approximate day when the world population reached eight billion people. [ 2 ]
HTML Form format HTML 4.01 Specification since PDF 1.5; HTML 2.0 since 1.2 Forms Data Format (FDF) based on PDF, uses the same syntax and has essentially the same file structure, but is much simpler than PDF since the body of an FDF document consists of only one required object. Forms Data Format is defined in the PDF specification (since PDF 1.2).
