We are very pleased to announce the release of version 1.2.0 "Hyacinthus orientalis" of GNU MPC, a C library for the arithmetic of complex numbers with arbitrarily high precision and correct rounding of the result, available from https://ftp.gnu.org/pub/gnu/mpc/
The release features the new functions mpc_sum and mpc_dot and several bug fixes, in particular to make functions more robust if the user reduces the exponent range. It also contains the tool mpcheck for easier comparison with computations by the C library on standard precision floating-point numbers. The library requires the presence of the recently released version 4.1.0 of GNU MPFR, and it is recommended to compile both with the most recent version 6.2.0 of GMP. We thank Jeffrey Walton, Dennis Clarke, Dagobert Michelsen and Rob "sisyphus" for extensive testing of the release candidate. Enjoy, Paul Zimmermann and Andreas Enge -- If you have a working or partly working program that you'd like to offer to the GNU project as a GNU package, see https://www.gnu.org/help/evaluation.html.
