* Note that this range is different from that for numeral input (page 197). 32768 is
displayed when the contents of the numeral memory table entry is 8000
H
(–32768), and 2147483648 is displayed when the contents of the memory table
entry is 80000000H (–2147483648). This is because when the value is unsigned,
only the sign is omitted and the numeric value is displayed as an absolute value. It
is not possible to input 32768 or 2147483648 as positive values.
Relationship between Contents of Host Words and Displayed Numeric
Value
When displaying the contents words allocated for a numeral memory table entry
in the host, the contents of the word is first converted to the format for storage in
the numeral memory table entry (signed hexadecimal), and then converted
again in accordance with the settings for Display Type and Display Sign settings
in order to display them. Therefore the result also differs according to the set-
tings made for Words and Storage Type.
