Etymology

Borrowed from Latin mantissa, mantīsa, of unknown origin (said by Festus to be a loanword from Etruscan, but it may actually be from Celtic, possibly through Etruscan mediation). Coincidentally, proparoxytone Greek μάντισσα (mántissa) means "female foreteller", as in χαρτομάντισσα (chartomántissa, “cartomancer”) or χειρομάντισσα (cheiromántissa, “chiromancer”).

Meanings

1. (obsolete) A minor addition to a text.
2. The part of a common logarithm after the decimal point, the fractional part of a logarithm.
3. The significand; that part of a floating-point number or number in scientific notation that contains its significant digits.
