Description
Clojure allows for numbers with a radix between 2 and 36.
Also, the BigInt N
suffix is allowed after a hexadecimal number.
From https://clojure.org/reference/reader#_literals:
When possible, they can be specified in any base with radix from 2 to 36 (see Long.parseLong()); for example 2r101010, 052, 8r52, 0x2a, 36r16, and 42 are all the same Long.
Here are some regex from [clojure.tools.reader] describing all numbers. (https://github.com/clojure/tools.reader/blob/master/src/main/clojure/clojure/tools/reader/impl/commons.clj#L46-L48)
(def ^Pattern int-pattern #"([-+]?)(?:(0)|([1-9][0-9]*)|0[xX]([0-9A-Fa-f]+)|0([0-7]+)|([1-9][0-9]?)[rR]([0-9A-Za-z]+)|0[0-9]+)(N)?")
(def ^Pattern ratio-pattern #"([-+]?[0-9]+)/([0-9]+)")
(def ^Pattern float-pattern #"([-+]?[0-9]+(\.[0-9]*)?([eE][-+]?[0-9]+)?)(M)?")
