+arbitrarily high precision and correct rounding of the result. It extends
+the principles of the IEEE-754 standard for fixed precision real floating
+point numbers to complex numbers, providing well-defined semantics for
+every operation. At the same time, speed of operation at high precision
+is a major design goal. The library is built upon and follows the same
+principles as GNU MPFR.")
