Suppose the number of characters is 8, the number of decimal places is 2, and the value is
-1.23456. The calculation is as follows.

( S1 +1 , S1 )
-1.23456

The value in S
If the value in S
and the number of characters which the integer part contains should be less than or
equal to 23.
If the value in S
value in S +2 plus 3 and 24, and the number of characters which the integer part
2
contains should be less than or equal to 22 minus the value in S

The value in S
0, it should be less than or equal to the value in S

If the floating-point number in S
floating-point number in S

If the length of the floating-point number is larger than the value in S
number is rounded off, and the redundant characters are deleted.

If the value in S
automatically.

If the length of the conversion result is less than the value in S
sign character and the real number are 16#20.

The conversion result ends with 16#00.
