6.1.6.5.3 Comparing Numeric and Nonnumeric Operands
The nonnumeric comparison rules, discussed above, apply. In addition, when numeric and nonnumeric operands are being compared, their USAGE must be the same. In such comparisons:
- The numeric operand must be described as an integer literal or data item.
- Non-integer literals and data items must not be compared with nonnumeric operands.
- X External floating-point items can be compared with nonnumeric
X operands.
- If the nonnumeric operand is a literal or an elementary data item, the
numeric operand is treated as though it were moved to an alphanumeric
elementary data item of the same size, and the contents of this
alphanumeric data item were then compared with the nonnumeric operand.
- If the nonnumeric operand is a group item, the numeric operand is
treated as though it were moved to a group item of the same size, and
the contents of this group item were compared then with the nonnumeric
operand.
