Script
Operation description
Converts the stored string starting at LDR200 to a decimal and stores the result in LDR100.
The number of digits that can be converted is the maximum number of digits for each data type with added sign.
If the string to convert contains NULL or characters that cannot be converted to numeric values, the string is
converted up to that character.
Setting the string “1234” (when the data type is UBIN16(W))
Setting the string “1234567” (when the data type is UBIN16(W))
Setting the string “-12345” (when the data type is BIN16(I))
String “1234567890” (when the data type is UBIN32(D))
■
Example 5.7.21 Convert string to decimal
[LDR 100] = ASCII2DEC([LDR 200]);
• This function can only be configured when UBIN16(W), BIN16(I), UBIN32(D), BIN32(L), BCD4(B)
or BCD8(EB) is specified as the Data Type.
• You can only specify an internal device.
• When using functions that handle strings, check the Storage Method of string data setting on the
System tab in the Project Settings dialog box. Depending on the setting, the upper and lower bytes
are stored in the reverse of the following explanation. For details, refer to Chapter 4 “3.1 System Tab” on
page 4-25.
