betweenclj/s
(between min max)Creates a predicate function for checking whether a number is between two values (inclusive).

decimal-string?clj/s
(decimal-string? s)Returns true if the string represents a decimal number.
Returns true if the string represents a decimal number.
digits?clj/s
(digits? s)Returns true if a string consists only of numerical digits.

email-address?clj/s
