• 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)  6". 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 + 7)".
• 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 equal to or smaller than the total number of digits minus 7.
• For example, when the total number of digits is "12", the number of digits of the decimal part is "4", and "-12.34567" is
specified, data is stored in (d) and later as shown below:

(1): Total number of digits
(2): Number of digits of decimal part
(3): Fixed to 2 digit
(4): Sign (integer part)
(5): Sign (exponent part)
(6): Single-precision real number
(7): "0000H" is automatically stored at the end of the character string.
• The converted character string data are stored in the device areas specified by (d) and later as shown below.
• As sign data of the integral part, "20H" (space) is stored if the single-precision real number is positive, and "2DH" (-) is stored if the data is negative.
• The integer part is fixed to 1 digit. "20H (space)" is stored between the integer part and the sign.

• If the decimal part of the single-precision real number data cannot be accommodated in the number of digits of the decimal part, lower digits of the
decimal part are rounded.
