My knowledge of mathematics says to me that if I attempt to perform (-5)^0.5, the result should be undefined, or some imaginary number (in this case ~ -2.23i). When I attempt to do this with rust:
The result is
-2.23606797749979, without anything to indicate that this is an imaginary number and would normally be undefined.
Is there an efficient way to determine whether or not
powf() results in an imaginary number/undefined result?
