Numeral Display
significant digit is treated as a sign or a numeral. With the NT21, NT31, NT31C,
NT631, and NT631C, however, the stored numeric value is converted for dis-
play according to the decimal/hexadecimal designation.
S For [Decimal], the number of digits entered in decimal fraction part is specified.
Since integers are stored in the numeral memory table entry, a decimal point is
appended according to this setting when a numeral is displayed.
