This function is used by Ignition's Expression language..


Tries to coerce value into a long (64-bit integer). If value is a number, the conversion is direct. If value is a string, it is parsed to see if it represents a long. If not, type casting fails. Will round if appropriate.


toLong(value, [failover])

  • Parameters

    • Object value - The value to type cast.

    • Object failover - The failover value if type casting fails. [optional]

  • Results

    • Long - The value type cast as a long.
