uint() function

The uint() function converts a single value to a UInteger.

Output data type: UInteger

uint(v: "4")

Parameters

v

The value to convert.

uint() behavior depends on the input data type:

Examples

• Convert a string to a uinteger value
• Convert a boolean to a uinteger value
• Convert a duration to a uinteger value
• Convert a time to a uinteger value
• Convert a float to a uinteger value
• Convert all values in a column to uinteger values

Convert a string to a uinteger value

uint(v: "3")

// Returns 3 (uint)

Convert a boolean to a uinteger value

uint(v: true)

// Returns 1

Convert a duration to a uinteger value

uint(v: 1m)

// Returns 160000000000

Convert a time to a uinteger value

uint(v: 2021-01-01T00:00:00Z)

// Returns 1609459200000000000

Convert a float to a uinteger value

uint(v: 10.12)

// Returns 10

Convert all values in a column to uinteger values

If updating values in the _value column, use toUInt(). To update values in columns other than _value:

1. Use map() to iterate over and update all input rows.
2. Use uint() to update the value of a column.

The following example uses data provided by the sampledata package.

import "sampledata"

data = sampledata.float()
  |> rename(columns: {_value: "foo"})

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