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 entry is converted as follows de-
pending on the setting for Display Type:
• Decimal:
The numeric value (signed binary data) stored in the numeral memory table
entry is converted to decimal notation.
• Hexadecimal:
The numeric value (signed binary data) stored in the numeral memory table
entry is displayed without alteration.
Reference: Numeral memory table entries store numeric values as signed binary data.
Effect of Sign on Conversion
For unsigned decimal values, if the result of conversion of the data in a numeral
memory table entry 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 –.
Permissible Display Range
The permissible display range depends on the settings made for Display Type
and Display Sign, as follows:
Display Type Sign Permissible Display Range
Decimal
Unsigned 0 to 2147483648
*
Decimal
Signed –2147483648 to 2147483647
Hexadecimal – 0 to FFFFFFFFH
When displaying the contents of host words allocated for numeral memory table
entries, not only the numeral display properties but also the Storage Type and
Words settings made for the numeral memory table entry have an effect on the
permissible display range. The permissible display range is determined as fol-
lows depending on these properties:
