i64.isI64(int64_string)           // true if a valid int64_string is passed
i64.asInt([integer])              // get/set value as Integer
i64.asHex([hex_string])           // get/set value as Hex
i64.config([config])              // get/set configuration

Big and Fast integer handling

Large integer string conversions are handled complements of alan/clarke/int-encoder.

Normal integers are handled by a faster radix converter.
