Additional remarks
1. If the length of the string in S exceeds 25 bytes and does not end with 16#00, SM0 is ON, and the error code in
SR0 is 16#2003.
2. There are some rules for the value in S. if the value in S does not follow the rules, the instruction is not executed,
SM0 is ON and the error code in SR0 is 16#2003.
The first ASCII code: signs16#2B(+), 16#2D(-), blank16#20, and numbers 16#30(0)–16#39(9) are allowed.
If the first ASCII code is a sign or a blank, the second ASCII code must be a number.
The second ASCII code can be in either decimal or exponential format.

Decimal format:
Integ er OR In tege r


Exponential format:
Inte ger Exp one nt
The decimal point "," (16#2E), can only occur once and there must be numbers before and after the decimal point.
There must be a number before the exponent.
Integers: only numbers "0" (16#30)–"9" (16#39) are allowed.
Decimals: only numbers "0" (16#30)–"9" (16#39) are allowed.
Exponents: The format for a four digit ASCII code is as below.
E OR e +OR-
There must be an "E" (16#45) or "e" (16#65) and it can only occur once.
There must be a sign "+"(16#2B) or "-" (16#2D) and it can only occur once.
