Processing details
• These instructions convert the character string in the device numbers specified by (s) and later to 32-bit binary data, and
store the number of digits in the device specified by (d1) and the binary data in the device specified by (d2). When
converting a character string into binary data, the data from the device number specified by (s) to a device number storing
"00H" is handled as a character string.
• The total number of digits stored in (d1) is the total number of characters (including the sign and decimal point) representing
the numeric value. The number of digits in the decimal part stored in (d1)+1 is the number of characters representing the
decimal part after 2EH (.). The 32-bit binary data stored in (d2) is binary value converted from a character string with the
decimal point ignored.

• The total number of characters of the character string specified by (s) is 2 to 13 characters.
• In the character string specified by (s), the number of characters that form the decimal part is 0 to 10 characters. However,
be sure to specify "Total number of digits - 3" or below.
• The range of the character string of the numeric value that can be converted to a binary value is -2147483648 to
2147483647 for a signed value with the decimal point ignored, and 0 to 4294967295 for an unsigned value. A character
string of a numeric value excluding the sign and decimal point can be specified only within the range of 30H to 39H. (Value
with the decimal point ignored ... "-12345.6" becomes "-123456".)
• When representing a positive numeric value, 20H is set in the sign, and when representing a negative numeric value, 2DH
is set.
• Set 2EH in the decimal point.
• When "20H (space)" or "30H (0)" exists between the sign and the first non-zero number in a character string specified by
(s), "20H" or "30H" is ignored during conversion to a binary value.
