7 APPLICATION INSTRUCTION
7.6 Character string operation instruction
■Decimal point format
• When 0 is specified in (s2), the decimal point format is applied.
• When the number of decimal part digits is 0, the number of digits that can be specified by (s2)+1 is "the number of digits (24
at a maximum)  2". For other than 0, the number of digits that can be specified by (s2)+1 is "the number of digits (24 at a
maximum)  (the number of decimal point digits + 3)".
• The number of digits in the decimal part that can be specified by (s2)+2 is 0 to 7. Note that the number of digits in the
decimal part must be smaller than the total number of digits minus 3.
• For example, when the total number of digits is "8", the number of digits of the decimal part is "3", and "-1.23456" is
specified, data is stored in (d) and later as shown below:
