7 APPLICATION INSTRUCTIONS
7.9 Real Number Instructions
• If 2BH(+) is specified for the sign or the sign is omitted in exponential format, the converted single-precision real number is
treated as a positive value. If 2DH(-) is specified for the sign in the exponent, it is treated as a negative value.
• If 20H (space) or 30H (0) exists between digits excluding the first 0 in the character string in the device specified by (s), the
instruction performs conversion by ignoring 20H and 30H.
• If 30H (0) exists between "E" and a numerical value in the character string in exponential format, the instruction performs
conversion by ignoring 30H.
Operation error
(1) Ignored.
(2) Single-precision real number
Error code
(SD0)
Description
2820H
00H does not exist within the range of the relevant device specified by (s).
3401H
An out-of-range value is set to (s).
• The integral part or decimal part contains a character other than 30H (0) to 39H (9).
• The specified string contains two or more 2EH (.)
• The exponent of the specified string contains a character other than 45H (E), 65H (e), 2BH (+), and 2DH (-).
• The specified string contains more than one exponent 45H (E) or 65H (e).
• The exponent in the specified string contains a numerical value consisting of three digits or more.
• The exponent of the specified string contains more than one sign 2BH (+) or 2DH (-).
• The specified string contains more than one sign 2BH (+) or 2DH (-) in the integral part of decimal point format or in the mantissa of
exponential format.
• The number of characters in the device specified by (s) and later is 0 or exceeds 24.
