Sqrt does not return 0 on negative parameter, documentation says otherwise

[Manadar]

A fault in the documentation, or in the implementation of the Sqrt function. The documentation describes it as:

Success: Returns the square-root.
Failure: Returns 0 and sets @error to 1 if parameter is negative.

This script says otherwise:
ConsoleWrite(Sqrt(-1) & @CRLF)

Output:
-1.#IND
