toUInt() function

The toUInt() function converts all values in the _value column to UIntegers.

Function type: Type conversion

toUInt()

Supported data types: Boolean | Duration | Float | Integer | Numeric String | Time

For duration and time values, toUint() returns the following:

Input typeReturned value
DurationThe number of nanoseconds in the specified duration
TimeA nanosecond epoch timestamp

To convert values in a column other than _value, define a custom function patterned after the function definition, but replace _value with your desired column.

from(bucket: "telegraf")
  |> filter(fn:(r) =>
    r._measurement == "mem" and
    r._field == "used"
  )
  |> toUInt()

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