The default data type for numeric controls in LabVIEW is double precision floating-point, often simply referred to as "Double." This choice is significant because double precision offers a broader range and higher precision for numerical values compared to other numeric types like integers or single precision floats. This allows for more accurate calculations, particularly in scenarios where precision is crucial, such as scientific computations and engineering applications.

In LabVIEW, when a numeric control is created, it is automatically set to this double precision type, enabling users to handle both very large and very small numbers effectively without requiring additional configuration. This default behavior is designed to simplify development and reduce the likelihood of overflow or underflow errors that may occur with other, less precise numeric types.

The other available data types, including integers, booleans, and strings, serve different purposes and are not suitable as the default for numeric controls, which specifically aim to handle real-valued numbers with precision and a wide range. Thus, the choice of double precision aligns with the common needs encountered in numerical programming tasks within LabVIEW.
