Ex-Device
5) Converted character string data is stored in and later as shown below.
- For the sign, "space" (20H) is stored when the 32-bit binary data stored in is positive, and "- (2DH)" is
stored when the 32-bit binary data stored in is negative.
- When the number of digits of the
decimal part +1 is set to any
value other than "0", the decimal point
"." (2EH) is automatically added in
"number of digits of decimal part +
1"th digit.
When the number of digits of the
decimal part +1 is set to "0",
the decimal point is not added.
- When the number of digits of the decimal
part +1 is larger than the number of
digits of 32-bit binary data stored in
[ +1, ], "0" (30H) is
automatically added, and the data is shifted
to the right end during conversion.
- When the number of all digits stored in
excluding the sign and decimal point
is larger than the number of digits of 32-bit
binary data stored in [ +1, ],
"space" (20H) is stored in each digit
between the sign and the numeric value.
When the number of all digits stored in
excluding the sign and decimal point is smaller than the number of digits of 32-bit binary data stored in
[ +1, ], 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.

Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
When the number of all digits stored in is outside the following range (error code: K6706)
When the number of digits of the decimal part stored in +1 is outside the following range (error code: K6706)
When the relationship between the number of all digits stored in and the number of digits of the decimal part
stored in +1 does not satisfy the following (error code: K6706)
(Number of all digits -3) Number of digits of decimal part
When the number of all digits stored in including the digit for sign and the digit for decimal point is smaller
than the number of digits of the binary data stored in [ +1, ] (error code: K6706)
When the devices and later storing a character string exceeds the corresponding device range (error code:
K6706)
