... The point is not users want to compare unassigned values. The point is that due to the input that may contain corner cases, unassigned values can be passed to comparison operators. To make the manual complete, the unassigned values should be added to the table.
No. The manual is complete. In section "6.3.2.1 String Type versus Numeric Type", a couple of paragraphs before the table of type comparisons, it states:
"Uninitialized variables also have the strnum attribute." So the table is complete. No need for an extra value type. Can you show an example that doesn't follow what the manual says? HTH. -- Manuel Collado - http://mcollado.z15.es
