This instruction uses a BIN floating point number at the to perform the conversion. By the format parameters
at the to convert each digit of that number become an ASCII code and combine those codes to a string, then
stores into the devices which are headed by .

2~24, the conversion could not exceed 24 characters.

The expanded number during the conversion
The positive or negative sign is using the 20H to represent positive; the 2DH represents negative.
The byte next to the positive or negative sign is a blank space, that will ll in the code 20H.
S2
If ( +2)=0, that indicates an integer will be shown, so there is no decimal point in the string; if ( +2)>0,
that indicates the number has a fractional part, so the decimal point will be added to the string.
S2
The expanded number 1.2346 is caused by to round off the content of next digit 6, hence that increases the
last used digit from 5 to 6.
When the expanded number converts to the ASCII codes, the instruction adds the end of string at the tail
automatically. If the set length of the string is an odd number, the end of string is 00H; in addition, the string
with even number set length will add the end of string 0000H. Thus, the D4 at the converted string with the
value 0000H that is the end of string.
