`int()` converts a value to an integer type.

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

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

##### Function type signature

## Parameters

### v
({{< req >}})
Value to convert.




## Examples

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

### Convert basic types to integers

```js
int(v: 10.12)

// Returns 10
int(v: "3")

// Returns 3
int(v: true)

// Returns 1
int(v: 1m)

// Returns 160000000000
int(v: 2022-01-01T00:00:00Z)// Returns 1640995200000000000


```


### Convert all values in a column to integers

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

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

```
