uint() function

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

uint() behavior depends on the input data type:

Input typeReturned value
bool1 (true) or 0 (false)
durationNumber of nanoseconds in the specified duration
floatUInteger equivalent of the float value truncated at the decimal
intUInteger equivalent of the integer
stringUInteger equivalent of the numeric string
timeEquivalent nanosecond epoch timestamp
Function type signature
(v: A) => uint

For more information, see Function type signatures.



(Required) Value to convert.


Convert basic types to unsigned integers

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.

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

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
