Processing details
■Operation processing
• When word (unsigned)/16-bit string type is specified for output argument.
Converts string type 4-character-string data input to (s) into BCD type data, and outputs the operation result from (d).
s
'9999'
String type
When '20H' (space) exists in the character string, the conversion is executed ignoring '20H'.
'20H' (space) and '30H' (0) in the character string are counted as one character.
The value to be input to (s) is string type data within the following range.
ASCII code: '30H' to '39H', '20H', and '00H'
When input character string has less than 4 letters, convert it with 4 letters supplementing with 0 to the end of the character
string. Therefore, when converting character string ("0001" for "1") with less than 4 letters to BCD data, input the zero padding
character strings.
When the character string has more than 4 letters, the conversion target is the forth character from the left of the character
string data.
