If x is a square root of y, then - x is also a square root of y. I think I know what you're trying to ask though. What you may be thinking of is that 0 to the 0th POWER is undefined (rather than 0 to the half power, the square root). One might naively say, aha! And then one might naively say, aha! Anything to the 0th power is 1, so 0 to the 0th power is 1.
And then one might further naively say, well, it's undefined, but it has to be either 0 or 1, it can't be anything else. But in fact 0 to the 0 is an indeterminate form that may evaluate to absolutely anything, much like 0 divided by 0, infinity divided by infinity, infinity minus infinity, or 1 to the infinity or negative infinity power.
- Zero times anything is zero, so this doesn't have an exception when you do the reverse to find the square root. The square root of a number (n) is a.

SOLUTION: Does the square root of 0 equal udefined, no solution. Does the square root of 0 equal udefined, no solution, or 0 Found 3 solutions by Alan3354. Under g++ version 4.8.0 (32-bit mingw), the square root of -0.0 (binary representation 0x8000000000000000) is NAN. But I could have sworn that earlier versions (I'm not sure which, but the last tim.
