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,
Though three individual computations are employed, the most of the arithmetic complexity restrain within the mantissa operations.
to add the mantissa terms, but the addition have to be done in accordance with the sign and exponent bits.
ii) Multiply the Mantissa of the two numbers, M = [A.
obtaining 1 at the MSB of the Mantissa of the Product.
Note that even though only 29 decimal digits of cos(100*Pi) are printed, the internal representation of its mantissa contains seven words: the precision has automatically been increased.
Shortening the mantissa is justified by the fact that there is no information available about the bits that would have followed.
Multiply the mantissas to produce the fraction of the result.
Very large and very small numbers can be stored in floating-point format, which consists of an exponent and mantissa.
According to IEEE Standard 754, 64-bit double-precision, floating-point arithmetic uses a mantissa of 52 bits, an exponent of 11 bits, and one sign bit [IEEE Standards Board 1985].
Figure 15 presents the bit width analysis for the 52-bit mantissa in double-precision floating-point multiplication.
Note that N is not necessarily the number of mantissa bits in the memory or register format.
Hence, for quad numbers represented in double-double format, N is the number of mantissa bits in a double.
