 Method (no overloads)

Summary

The logarithmic integral, li(z) = Ei(ln z), with the principal logarithm, at the
working precision, for every complex z: li(0) = 0 and li(1) = -oo.

Remarks

On x > 0 it is the principal value of int_0^x dt/ln t, real, and on
0 < x < 1, where ln x is negative, Ei of a negative number.
The logarithm is taken with ten more digits, so that Ei is asked the argument to
the precision it answers in.
