# Relational expressions

A relational expression evaluates to 1 if the relation is true,
and evaluates to 0 if the relation is false. Relational operators
have lower precedence than all arithmetic and string operators.
Therefore, relational operators are only evaluated after all
arithmetic and string operations have been evaluated.

If one operand is numeric and one operand is string, both
operands are treated as strings. To resolve a numeric relation, the
values of the expression are compared. To resolve a string
relation, the characters in each string are compared one at a time
from leftmost characters to right-most. If no unequal character
pairs are found, the strings are considered to be equal.

If the two strings are not the same length, and the shorter
string is otherwise identical to the beginning of the longer
string, the longer string is considered greater than the shorter
string.

The resolution of unequal character pairs depends on the
characters. If the unequal pair of characters are nonalphabetical
characters, the characters are ranked according to their numeric
ASCII code equivalents. The string contributing the higher numeric
ASCII code equivalent is considered to be greater than the other
string. If the unequal pair of characters are alphabetical, the
pair is ranked in strict alphabetical order.

If one of the characters is alphabetical and the other character
is nonalphabetical, the characters are ranked according to the
numeric ASCII value of the uppercase letter, even if the letter is
in lowercase, and the numeric ASCII value of the nonalphabetical
character.
