If the source string contains more than seven characters excluding the sign, decimal point, and exponent,
the eighth character and subsequent ones are discarded.

●
In decimal form, if the sign is encoded into 2BH (plus sign) in [S] or omitted, the string is converted to
a positive number. If the sign is encoded into 2DH (minus sign), the string is converted to a negative
number.
●
In exponential form, if the sign of the exponent is encoded into 2BH (plus sign), the string is converted
to a positive exponent after the sign is omitted. If the sign is encoded into 2DH (minus sign), the string
is converted to a negative exponent.
●
If the source string contains spaces (20H) or 0s (30H) between digits other than the initial 0, 20H or
30H is ignored when the string is converted.

Errors
An operation error occurs in the following conditions. The error ag M8067 is set ton ON to identify this
error and the error code is stored in D8067.
• The integer and fractional parts contain characters out of the range 0 (30H) to 9 (39H). (Error code: K6706)
• The string from head address [S] contains two or more decimal points (2EH). (Error code: K6706)
• The exponent contains characters other than E (45H), plus sign (2BH), and minus sign (2DH), or multiple
exponents exist. (Error code: K6706)
• Elements from head address [S] do not contain 00H. (Error code: K6705)
• The number of characters after [S] is 0 or exceeds 24. (Error code: K6705)
