# op:numeric-equal - XPath XQuery Reference

Returns true if and only if the value of $arg1 is equal to the value of
               $arg2.Defines the semantics of
         the "eq" operator when applied to two numeric values, and is also used in defining the
         semantics of "ne", "le" and "ge".General rules: see  and . For xs:float and xs:double values, positive zero and negative
            zero compare equal. INF equals INF, and -INF
            equals -INF. NaN does not equal itself.
