Usage considerations

Referencing data types

• To retrieve the type number, use typeof(x), where x is a value of the intended type, or reference a type with type!{namespace}type-name (within single quotes).
• When referencing a data type, consider the impact that deleting the data type has on the expression that references it.

Examples

Returning data type name

1
typename(27)

Returns User or Group.

1
typename(type!Integer)

Returns Number (Integer).

Returning multiple data type names

1
typename(type!Integer, type!Decimal, type!User)

Returns {"Number (Integer)", "Number (Decimal)", "User"}. Multiple input values are supported.

1
typename({type!Integer, type!Decimal, type!User})

Returns {"Number (Integer)", "Number (Decimal)", "User"}. A list of inputs is supported.

  typeof(
    "abc",
    0.5,
    47,
    date(1985, 12, 10),
    a!map(first: 1, second: 2),
    {order: 1906, units: 46}
  )
)

Returns { "Text", "Number (Decimal)", "Number (Integer)", "Date", "Map", "Dictionary" }. typeof returns a list of type numbers, which is evaluated and returned as a list of type names.

Returning list type names for lists

1
typename(typeof({ 1, 2, {}, 17 }))

Returns List of Number (Integer).

1
typename(typeof({ 1, 2, {}, 17 }), typeof({ 1.0, 2.2, 17.0 }))

Returns { List of Number (Integer), List of Number (Floating Point) }.
