Relational Operators

The relational operators perform numeric comparisons if both operands are numbers. Otherwise, they perform string comparisons (that is, lexical, dictionary ordering). A string is considered a number if it consists of only digits, the minus sign, or a period. No white space is allowed. PSL relational operators do not consider constants in C-like exponential notation (such as 2.3e+27) as numbers. The following table lists the PSL relational operators.
