## hex {#hex}
接受`String``unsigned integer``Date`或`DateTime`类型的参数。返回包含参数的十六进制表示的字符串。使用大写字母`A-F`。不使用`0x`前缀或`h`后缀。对于字符串,所有字节都简单地编码为两个十六进制数字。数字转换为大端(«易阅读»)格式。对于数字,去除其中较旧的零,但仅限整个字节。例如,`hex1='01'`。 `Date`被编码为自Unix时间开始以来的天数。 `DateTime`编码为自Unix时间开始以来的秒数。
返回包含参数的十六进制表示的字符串。
## unhex(str) {#unhexstr}
别名为: `HEX`
接受包含任意数量的十六进制数字的字符串并返回包含相应字节的字符串。支持大写和小写字母A-F。十六进制数字的数量不必是偶数。如果是奇数则最后一位数被解释为00-0F字节的低位。如果参数字符串包含除十六进制数字以外的任何内容则返回一些实现定义的结果不抛出异常
如果要将结果转换为数字可以使用«reverse»和«reinterpretAsType»函数。
**语法**
``` sql
hex(arg)
```
该函数使用大写字母`A-F`,不使用任何前缀(如`0x`)或后缀(如`h`
对于整数参数,它从高到低(大端或“人类可读”顺序)打印十六进制数字(“半字节”)。它从左侧第一个非零字节开始(省略前导零字节),但即使前导数字为零,也始终打印每个字节的两个数字。
类型为[Date](../../sql-reference/data-types/date.md)和[DateTime](../../sql-reference/data-types/datetime.md)的值将被格式化为相应的整数(日期为 Epoch 以来的天数DateTime 为 Unix Timestamp 的值)。
对于[String](../../sql-reference/data-types/string.md)和[FixedString](../../sql-reference/data-types/fixedstring.md),所有字节都被简单地编码为两个十六进制数字。零字节不会被省略。
类型为[Float](../../sql-reference/data-types/float.md)和[Decimal](../../sql-reference/data-types/decimal.md)的值被编码为它们在内存中的表示。由于我们支持小端架构,它们以小端编码。零前导尾随字节不会被省略。
类型为[UUID](../data-types/uuid.md)的值被编码为大端顺序字符串。
**参数**
- `arg` — 要转换为十六进制的值。类型为[String](../../sql-reference/data-types/string.md)[UInt](../../sql-reference/data-types/int-uint.md)[Float](../../sql-reference/data-types/float.md)[Decimal](../../sql-reference/data-types/decimal.md)[Date](../../sql-reference/data-types/date.md)或者[DateTime](../../sql-reference/data-types/datetime.md)。

## unhex {#unhexstr}
执行[hex](#hex)函数的相反操作。它将每对十六进制数字(在参数中)解释为一个数字,并将其转换为该数字表示的字节。返回值是一个二进制字符串 (BLOB)。

- `arg` — 整数值。类型为[Int/UInt](../../sql-reference/data-types/int-uint.md)。
**返回值**
- 包含等于 `1` 的位位置列表的数组,按升序排列。
类型为: [Array](../../sql-reference/data-types/array.md)([UInt64](../../sql-reference/data-types/int-uint.md))。
**示例**
查询语句:
``` sql
SELECT bitPositionsToArray(toInt8(1)) AS bit_positions;
```
结果:
``` text
┌─bit_positions─┐
│ [0] │
└───────────────┘
```
查询语句:
``` sql
SELECT bitPositionsToArray(toInt8(-1)) AS bit_positions;
```
结果:
``` text
┌─bit_positions─────┐
│ [0,1,2,3,4,5,6,7] │
└───────────────────┘
```
