Suppose the number of characters is 12, the number of decimal places is 4, and the value is
-12.34567. The calculation is as follows.


The integer part contains one character. To fulfill the number of characters, the codes
between the sign code and the integer part are 16#20.

If the value in S
automatically.

If the exponent is a positive number, the sign code in D is 16#2B. If the exponent is a
negative number, the sign code in D is 16#2D.

The exponent part contains two characters. If there is only one character, the other
character is "0" (16#30).

The conversion result ends with 16#00.
