①
The value in [S1] ranges from 2 to 8.
②
The value in [S1+1] ranges from 0 to 5. The value in [S1+1] must be less than or equal to the value in [S1]
minus 3.
③
The 16-bit BIN number ranges from –32,768 to +32,767. The string after conversion is stored in
elements from head address [D].
• When the 16-bit BIN number in [S2] is positive, the sign is encoded into 20H (space); when it is
negative, the sign is encoded into 2DH (minus sign).
• When a number other than 0 is set in [S1+1], a decimal point (2EH) is inserted at the immediate
position prior to a number of characters indicated by [S1+1].
• No decimal point is inserted when the value in [S1+1] is 0.

• If the value in [S1+1] is greater than the number of characters contained in the 16-bit BIN number in [S2],
the system aligns characters to the right and then adds 0s (30H) on the left.

• With the decimal point and sign excluded, if the total number of characters indicated by [S1] is greater
than the number of characters contained in the 16-bit BIN number in [S2], spaces (20H) are inserted
between the sign and the value.
• An error will occur when the number of characters contained in the 16-bit BIN number in [S2] is greater.
