EnglishEdit
EtymologyEdit
Borrowed from Latin mantissa, mantīsa, of unknown origin (said by Festus to be a loanword from Etruscan, but it may actually be from Celtic,^{[1]} possibly through Etruscan mediation).
NounEdit
mantissa (plural mantissas or mantissae)
- (obsolete) A minor addition to a text.
- (mathematics) The part of a common logarithm after the decimal point, the fractional part of a logarithm.
- (mathematics, computing, proscribed) The significand; that part of a floating-point number or number in scientific notation that contains its significant digits.
Usage notesEdit
The use of mantissa to refer to significant digits in a floating point number or scientific notation is discouraged by some in favor of significand, due to earlier distinct usage for the logarithm. It remains in widespread use in the US, however.
TranslationsEdit
part of a logarithm after the decimal point
