Precautions
• Store sign data, "space (20H)" or "- (2DH)" in the 1st byte (low-order 8 bits of the head device set in (s)). Only the ASCII
data "0 (30H)" to "9 (39H)", "space (20H)" and "decimal point (2EH)" can be stored from the 2nd byte to the "00H" at the
end of the character string in (s). If "- (2DH)" is stored in the 2nd byte or later, an operation error occurs.
