The decimal part of a logarithm. In the logarithm 2.95424, the mantissa is 0.95424.

[Latin, makeweight, perhaps of Etruscan origin.]

mantissa

(mænˈtɪsə)
n
(Mathematics) the fractional part of a common logarithm representing the digits of the associated number but not its magnitude: the mantissa of 2.4771 is .4771. Compare characteristic2a
[C17: from Latin: something added, of Etruscan origin]

man•tis•sa

(mænˈtɪs ə)

n., pl. -sas.
the decimal part of a common logarithm. Compare characteristic (def. 3a).
[1860–65; < Latin, variant of mantisa addition; because additional to the characteristic part]

man·tis·sa

(măn-tĭs′ə)
The part of a logarithm to the base ten that is to the right of the decimal point. For example, if 2.749 is a logarithm, .749 is the mantissa. Compare characteristic.
