MPSolve output


Output format

The output format is mainly controlled by the -Ox command line option as follows (here re and im denote real and imaginary parts of the root, respectively):

Output conventions

In order to give the user as much information as possible, the numbers MPSolve outputs are formatted according to the following rules: (in the following din and dout stand for the given input precision and the requested output precision) The uncertainty about the zero output is present also in the case of polynomial having approximate input coefficients. In fact, it may happen that the root neighborhood of p(x) intersects zero. In this case the program outputs 0.0 for those approximations belonging to the connected component of the root neighborhood that intersects zero. However, this (nonzero) approximations are reported integrally in the standard error if the -d (debug) switch is set .

Status of the approximations

The status of each approximation is also output when the full output is requested with the -Of option (see the options page).

The status of a root is formed by three characters:
