## mantissa

[man′tis·ə]
(computer science)
A fixed point number composed of the most significant digits of a given floating-point number. Also known as fixed-point part; floating-point coefficient.
(mathematics)

## mantissa

(programming)
The part of a floating point number which, when multiplied by its radix raised to the power of its exponent, gives its value. The mantissa may include the number's sign or this may be considered to be a separate part.

A new square tile is formed from elements from two matrices--one that holds the 16 bit fixed-point values which represent the mantissas and the other smaller matrix that contains the exponents as 8bit integers for each tile.
Amongst the steps of floating-point multiplier, the more resource consuming part is the mantissa multiplier.
2- The second part is "584" which is located after the Decimal Point, and it is called the Fractional Part or Mantissa.
The steps got more complicated when small numbers were involved, too, such as finding [square root of 0.52], since the logarithm of 0.52 was generally first written with a characteristic of "bar 1" to avoid dealing with some aspects of negative numbers, while leaving the mantissa positive:
In IEEE754 a real number X has to be represented in 32 bits with a sign bit (s) followed by eight exponent bit (E) and twenty three mantissa (m) bits, and is given by,
The CUCA also signed a '2 plus 2' academic collaborative partnership with Mantissa College, Malaysia, whereby students with majors in marketing can complete their bachelor degree at Mantissa, after completion of two years at the CUCA.
ii) Multiply the Mantissa of the two numbers, M = [A.sub.m] * [B.sub.m]
Each finite number is described by three fields: s a sign represented on one bit (1 indicating negative), e a biased exponent represented on 11 bits and m a mantissa represented on 52 bits (see Figure 1).
The display of floating-point numbers comprises two parts the significant (or mantissa) M and the exponent E.
In our case we used 50 decimal digits for the mantissa, which is in accordance with the number of decimal digits employed in the computation of Gauss-Turan nodes.
