**Description**

Converts the input value to a long. If the input parameter is of a date type, its value will be interpreted as milliseconds since the [Unix epoch](https://en.wikipedia.org/wiki/Unix_time), converted to long. Boolean `true` will be converted to long `1`, `false` to `0`.

When given two arguments, a string value and a whole number base,
the string is parsed as a long in the given base.
If parsing fails a warning is generated as described below and the result is null.
A leading '0x' prefix is allowed for base 16.
