Decimal the Roman numerals did, an intermediate base of 5. Notably, the polymath Archimedes (ca. 287–212 BC) invented a decimal positional system in his Sand Reckoner which was based on 10 and later led the German mathematician Carl Friedrich Gauss to lament what heights science would have already reached in his days if Archimedes had fully realized the potential of his ingenious discovery. The Hittites hieroglyphs (since 15th century BC), just like the Egyptian and early numerals in Greece, was strictly decimal. Some non-mathematical ancient texts like the Vedas dating back to 1900–1700 BCE make use of decimals and mathematical decimal
Binary integer decimal Binary integer decimal The IEEE 754-2008 standard includes an encoding format for decimal floating point numbers in which the significand and the exponent (and the payloads of NaNs) can be encoded in two ways, referred to in the draft as binary encoding and "decimal encoding". Both formats break a number down into a sign bit "s", an exponent "q" (between "q" and "q"), and a "p"-digit significand "c" (between 0 and 10−1). The value encoded is (−1)×10×"c". In both formats the range of possible values is identical, but they differ in how the significand "c" is represented. In the decimal
