In 1946, Arthur Burks used the terms mantissa and characteristic to describe the two parts of a floating-point number (Burks [11] et al.) by analogy with the then-prevalent common logarithm tables: the characteristic is the integer part of the logarithm (i.e. the exponent), and the mantissa is the fractional part.
Mantissa (/ m æ n ˈ t ɪ s ə /) may refer to: Mantissa (logarithm), the fractional part of the common (base-10) logarithm; Significand (also commonly called mantissa), the significant digits of a floating-point number or a number in scientific notation; Mantissa (band) Mantissa, a 1982 novel by John Fowles; Mantissa College
The fractional part is known as the mantissa. [ b ] Thus, log tables need only show the fractional part. Tables of common logarithms typically listed the mantissa, to four or five decimal places or more, of each number in a range, e.g. 1000 to 9999.
A signed (meaning positive or negative) digit string of a given length in a given base (or radix). This digit string is referred to as the significand, mantissa, or coefficient. [nb 1] The length of the significand determines the precision to which numbers can be represented. The radix point position is assumed always to be somewhere within the ...
A 2-bit float with 1-bit exponent and 1-bit mantissa would only have 0, 1, Inf, NaN values. If the mantissa is allowed to be 0-bit, a 1-bit float format would have a 1-bit exponent, and the only two values would be 0 and Inf. The exponent must be at least 1 bit or else it no longer makes sense as a float (it would just be a signed number).
An ancient symbol of a unicursal five-pointed star circumscribed by a circle with many meanings, including but not limited to, the five wounds of Christ and the five elements (earth, fire, water, air, and soul). In Satanism, it is flipped upside-down. See also: Sigil of Baphomet. Rose Cross: Rosicrucianism / Hermetic Order of the Golden Dawn
