Function
1) 16-bit operation (VAL and VALP)
① The string stored in elements from head address [S] is converted to a 16-bit BIN number. The total
number of characters contained in the string is stored in [D1], and the number of characters in the
fractional part is stored in [D+1]. The BIN number is stored in [D2].
② During the string-to-BIN conversion, the data within the range from [S] to the element that stores 00H
is processed as a string.

③ String to be converted
• The total number of characters contained in the string to be converted and its value (with the decimal point
ignored) must be within the following ranges:
Setting Range
Total number of characters 2 to 8
Number of characters in the
fractional part
0 to 5
Value range (with the decimal
point ignored)
–32,768 to +32,767
For example, 123.45 is
processed as 12345.
• Types of characters to be converted
Character Type
Positive number Space (20H)
Negative number Minus sign (2DH)
Decimal point Period (2EH)
Digit 0 (30H) to 9 (39H)
④ [D1] indicates the total number of characters, including the digits, sign, and decimal point.
⑤ [D1+1] indicates the number of characters in the fractional part, that is, the characters to the right of the
decimal point (2EH).
⑥ [D2] stores the 16-bit BIN number converted from a string with the decimal point ignored.
When a string is converted to a 16-bit BIN number, the spaces (20H) or 0s (30H) between the sign and a
set of digits other than 0 are ignored.
