bool() converts a value to a boolean type.
Function type signature
(v: A) => bool
For more information, see Function type signatures.
Parameters
v
(Required) Value to convert.
Examples
- Convert strings to booleans
- Convert numeric values to booleans
- Convert all values in a column to booleans
Convert strings to booleans
bool(v: "true")
// Returns true
bool(v: "false")// Returns false
Convert numeric values to booleans
bool(v: 1.0)
// Returns true
bool(v: 0.0)
// Returns false
bool(v: 1)
// Returns true
bool(v: 0)
// Returns false
bool(v: uint(v: 1))
// Returns true
bool(v: uint(v: 0))// Returns false
Convert all values in a column to booleans
If converting the _value column to boolean types, use toBool().
If converting columns other than _value, use map() to iterate over each
row and bool() to convert a column value to a boolean type.
data
|> map(fn: (r) => ({r with powerOn: bool(v: r.powerOn)}))
