Standard inequality symbols such as , ≤, =, ≠, >, ≥, and so on are also used in set notation. Using the same example as above, the domain of f(x) = x 2 in set notation is: {x | x∈ℝ} The above can be read as "the set of all x such that x is an element of the set of all real numbers." In other words, the domain is all real numbers.

Square roots of positive numbers are not in general rational numbers, and so cannot be written as a terminating or recurring decimal expression.
