Now "move" digits around the decimal dot according to the exponent value,
and add necessary zeros.
Examples :
- 1E+3 : needs 3 more zeros at the left of '.' (int_digits_added_zeros=3)
- 1E-3 : '1' moves at the right of '.', and 2 more zeros are needed
between '.' and '1'
- 1234.5E-3 : '234' moves at the right of '.'
These moves are implemented with pointers which point at the begin
and end of each moved segment. Examples :
- 1234.5E-3 : before the code below is executed, the int_digits part is
from '1' to '4' and the frac_digits part from '5' to '5'. After the code
below, the int_digits part is from '1' to '1', the frac_digits_head
part is from '2' to '4', and the frac_digits part from '5' to '5'.
- 1234.5E3 : before the code below is executed, the int_digits part is
from '1' to '4' and the frac_digits part from '5' to '5'. After the code
below, the int_digits part is from '1' to '4', the int_digits_tail
part is from '5' to '5', the frac_digits part is empty, and
int_digits_added_zeros=2 (to make 1234500).
