# uint() function

-   Flux 0.7.0+
-   View InfluxDB support

`uint()` converts a value to an unsigned integer type.

`uint()` behavior depends on the input data type:

| Input type | Returned value |
| --- | --- |
| bool | 1 (true) or 0 (false) |
| duration | Number of nanoseconds in the specified duration |
| float | UInteger equivalent of the float value truncated at the decimal |
| int | UInteger equivalent of the integer |
| string | UInteger equivalent of the numeric string |
| time | Equivalent nanosecond epoch timestamp |

##### Function type signature

```js
(v: A) => uint
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### v

(Required) Value to convert.

## Examples

-   [Convert basic types to unsigned integers](#convert-basic-types-to-unsigned-integers)
-   [Convert all values in a column to unsigned integers](#convert-all-values-in-a-column-to-unsigned-integers)

### Convert basic types to unsigned integers

```js
uint(v: "3")

// Returns 3
uint(v: 1m)

// Returns 160000000000
uint(v: 2022-01-01T00:00:00Z)

// Returns 1640995200000000000
uint(v: 10.12)

// Returns 10
uint(v: -100)// Returns 18446744073709551516

```

### Convert all values in a column to unsigned integers

If converting the `_value` column to uint types, use `toUInt()`. If converting columns other than `_value`, use `map()` to iterate over each row and `uint()` to convert a column value to a uint type.

```js
data
    |> map(fn: (r) => ({r with exampleCol: uint(v: r.exampleCol)}))
```
