/* The mp_no structure holds the details of a multi-precision floating point

number.
|
|
|
|
- The radix of the number (R) is 2 ^ 24.
|
|
|
|
- E: The exponent of the number.
|
|
|
|
- D[0]: The sign (-1, 1) or 0 if the value is 0. In the latter case, the
|
|
values of the remaining members of the structure are ignored.
|
|
|
|
- D[1] - D[p]: The mantissa of the number where:
|
|
|
|
0 <= D[i] < R and
|
|
P is the precision of the number and 1 <= p <= 32
|
|
|
|
D[p+1] ... D[39] have no significance.
|
|
|
|
- The value of the number is:
|
|
|
|
D[1] * R ^ (E - 1) + D[2] * R ^ (E - 2) ... D[p] * R ^ (E - p)
