- When the number of all digits stored in
S excluding the sign and decimal
1
point is larger than the number of digits of
16-bit binary data stored in
"space" (20H) is stored in each digit
between the sign and the numeric value.
When the number of all digits stored in
S excluding the sign and decimal point is smaller than the number of digits of 16-bit binary data stored in
1
S , an error is caused.

- "00H" indicating the end of a character string is automatically stored at the end of a converted character string.
When the number of all digits is even, "0000H" is stored in the device after the last character.
When the number of all digits is odd, "00H" is stored in the high-order byte (8 bits) of the device storing the final
character.
