+ | ===== Bases ===== | ||

+ | The parsed numbers can be written in any base from 2 to 36. In bases over 10, letters of the alphabet are used as digits. | ||

+ | |||

+ | If a base is not explicitly specified or is set to 0, base prefixes can be used: | ||

+ | * '' | ||

+ | * '' | ||

+ | * '' | ||

+ | |||

+ | For example, '' | ||

+ | |||

+ | If no base prefix is present, base 10 is used by default | ||

+ | |||

+ | If a base is specified when parsing the number, base prefixes are **not** supported and their presence is treated as error. | ||
