toUInt() function

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

*Function type: Type conversion*

  1. toUInt()

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

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

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.
