In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators B...
(If you do not want complex approximate solutions, ignore the complex approximate solutions; that still leaves two real approximate solutions.) This approximation improves "as fast as" $-1/x$ becomes negligible in your application.
@DeanMiller: I think it helps, but it is a bit confusing as the OP uses a definition of approximate spectrum that differs from Wikipedia's but which according to the addendum of the accepted answer is equivalent. However, this is not the definition used in the main part of the answer! Moreover, they don't show the equivalence but only the implication in one direction.
From the book "Numerical Methods for Engineers", by Steven C. Chapra, they state the true error is always less than the approximate error, and therefore, it is safe ...

Where insufficient data exist to establish the value of a given variable accurately, attempts may be made to estimate 1 this value. The process is called estimation 2 and the resulting value an estimate 3.
