Any way of calculating square root of a negative number on HP 35S?

There is a simple rule:
The 35s usually tries to return a real result. If no real result exists, it returns an error.
But if at least one argument is complex, it returns a complex result.

So there is an easy solution: use 0,5 i 0 y^x.

–2 [ENTER] 0,5 i 0 [y^x] => 0 i 1,4142....

That method works with the power function, but does not work with the sqrt key if one enters -2 i 0 and then chooses the sqrt key. So entering a number using complex input does not work for all functions.
