Relational operators

7.25 Relational operators

Relational operators act on two operands of the same type to produce a logical value.

The operands can be one of:
  • Numeric.
  • PC-relative.
  • Register-relative.
  • Strings.
Strings are sorted using ASCII ordering. String A is less than string B if it is a leading substring of string B, or if the left-most character in which the two strings differ is less in string A than in string B.
Arithmetic values are unsigned, so the value of 0>-1 is {FALSE}.
The following table shows the relational operators:
