Weball of whose roots are complex. When we apply Graeffe's method to an equation whose roots are complex, we get directly not the roots themselves but their absolute values. To determine the roots we must have recourse to the original equation and to the explicit expressions of the elementary symmetric functions of the roots of the equation. WebMar 3, 2024 · After getting +/-0, nan, inf, and negatives out of the way, it works by decomposing the float into a mantissa in the range of [ 1 / 4, 1) times 2 e where e is an even integer. The answer is then sqrt (mantissa)* 2 e/2. Finding the sqrt of the mantissa can be guessed at with a least squares quadratic curve fit in the range [ 1 / 4, 1]. Webtion. Kopal [6] illustrate the method as the best way of extract-ing complex roots. Scarborough [7] said, “Probably the root squaring method of Graeffe is the best to use in “most cases”. This method gives all the roots at once, both real and complex. But he did not mention the “cases”. Carnahan et al [8] emphat- fittest states 2021
