Numeral Display
Reference: Numeral memory tables store numeric values as signed binary data.
Example: Displaying "123456"
- Setting for "Integer" = 8; setting for "Decimal" = 0:
Resulting display: 00123456
- Setting for "Integer" = 4; setting for "Decimal" = 4:
Resulting display: 0012.3456
- Setting for "Integer" = 2, setting for "Decimal" = 4:
Resulting display: 12.3456
- Setting for "Integer" = 1, setting for "Decimal" = 4:
Resulting display: ∗.∗∗∗∗
S Zero suppression
The numeric value is displayed right-justified within the sum of the number of
digits specified for "Integer" and the number of digits specified for "Decimal".
Normally, when the number of digits of the numeric value is small, the excess
digits at the left side are filled with zeros. When the check mark is set for "Zero
Suppression", no zeros are set in the excess digits and they remain blank.
Without zero suppression
(when the number of digits displayed is 8)
S Stored data and displayed numeric value
The conversion method for display and the range of numeric values that can be
displayed depend on the following settings.
Display Type ("Decimal"/"Hexadecimal")
Display Sign (whether or not negative values are displayed)
<Conversion depending on "Display Type">
The data stored in a numeral memory table is converted as follows depending on
the setting for "Display Type".
- "Decimal":
The numeric value (signed binary data) stored in the numeral memory table is
converted to decimal notation.
- "Hexadecimal":
The numeric value (signed binary data) stored in the numeral memory table is
displayed without alteration.
<Effect of sign on conversion>
For unsigned decimal values, if the result of conversion of the data in a numeral
memory table is negative, it is displayed after conversion to an absolute value.
For signed decimal values, if the result of conversion is a negative value it is dis-
played with a minus sign "−".
With zero suppression
