Maps of agreement of approximations of natural tetration with elementary functions fima and maclo, used in the implementation fsexp.cin.

Left: $D=D_6(x\!+\!\mathrm i y)$;

$\displaystyle D_6(z)= - \ln \left( \frac

\right)$ right: $D=D_7(x\!+\!\mathrm i y)$; $\displaystyle D_7(z)= - \ln \left( \frac
\right)$ Levels $D=\mathrm{const}$ are drawn with step 2, but the exception is dome for level $D=1$, this level is drawn with thick lines. Usage: this is figure 14.10 of the book Суперфункции (2014, In Russian) [1]; the English version is in preparation in 2015. First time published in the Vladikavkaz Matehmatical Journal[2].
