    en.wikipedia.org/wiki/Mathematical_Alphanumeric...

    Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific, fixed meanings in particular areas of mathematics.

  4. Greek numerals - Wikipedia

    en.wikipedia.org/wiki/Greek_numerals

    Greek numerals are decimal, based on powers of 10. The units from 1 to 9 are assigned to the first nine letters of the old Ionic alphabet from alpha to theta . Instead of reusing these numbers to form multiples of the higher powers of ten, however, each multiple of ten from 10 to 90 was assigned its own separate letter from the next nine ...

    en.wikipedia.org/wiki/Drekavac

    The drekavac was originally thought to have come from the souls of sinful men, or from children who died unbaptised. [2]It was popularly believed to be visible only at night, especially during the twelve days of Christmas (called unbaptised days in Serbo-Croatian) and in early spring, when other demons and mythical creatures were believed to be more active. [2]

  7. Bi-quinary coded decimal - Wikipedia

    en.wikipedia.org/wiki/Bi-quinary_coded_decimal

    Bi-quinary coded decimal is a numeral encoding scheme used in many abacuses and in some early computers, notably the Colossus. [2] The term bi-quinary indicates that the code comprises both a two-state (bi) and a five-state (quinary) component. The encoding resembles that used by many abacuses, with four beads indicating the five values either ...

  8. Decimal representation - Wikipedia

    en.wikipedia.org/wiki/Decimal_representation

    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".

    log 10 (3.000 × 10 4) = log 10 (10 4) + log 10 (3.000) = 4.000000... (exact number so infinite significant digits) + 0.477 1 212547... = 4.477 1 212547 ≈ 4.4771. When taking the antilogarithm of a normalized number, the result is rounded to have as many significant figures as the significant figures in the decimal part of the number to be ...
