Note that tests might need the package installed.
Changes in version 1.0.1:
- Switched to automake 1.11.6, see
https://lists.gnu.org/archive/html/automake/2012-07/msg00023.html
- #14669: Fixed extraction of CC from gmp.h
- Fixed case of intermediate zero real or imaginary part in mpc_fma,
found by hydra with GMP_CHECK_RANDOMIZE=1346362345
Changes since version 0.9:
- First release as a GNU package
- License change: LGPLv3+ for code, GFDLv1.3+ (with no invariant sections)
for documentation
- 100% of all lines are covered by tests
- Functions renamed:
mpc_mul_2exp to mpc_mul_2ui, mpc_div_2exp to mpc_div_2ui
- 0^0, which returned (NaN,NaN) previously, now returns (1,+0)
- Removed compatibility with K&R compilers, untestable due to lack of
such compilers
- New functions: mpc_log10, mpc_mul_2si, mpc_div_2si
- Speed-ups:
- mpc_fma
- Bug fixes:
- mpc_div and mpc_norm now return a value indicating the effective
rounding direction, as the other functions
- mpc_mul, mpc_sqr and mpc_norm now return correct results even if there
are over- or underflows during the computation
- mpc_asin, mpc_proj, mpc_sqr: Wrong result when input variable has
infinite part and equals output variable is corrected
- mpc_fr_sub: Wrong return value for imaginary part is corrected
Prompted by Stathis Kamperis.
Changes:
* New functions
+ mpc_set_dc, mpc_set_ldc, mpc_get_dc, mpc_get_ldc for
converting between mpc type variables and C variables of
type double _Complex or long double _Complex
+ mpc_sin_cos, computing simultaneously the sine and cosine
* Speed-ups
+ mpc_pow_si through binary exponentiation
+ mpc_pow_z when the exponent fits in a long
+ mpc_tan through the use of mpc_sin_cos
* Bug fixes
+ trigonometric functions: infinite loop due to overflow for large arguments
+ exp: close to infinite loop for argument close to 0
+ sqrt: close to infinite loop for argument close to 1
+ add_si: replaced macro by function, since the macro evaluated the same expression twice
* Logging feature for debugging
./configure --enable-logging
#include "mpc-log.h" instead of #include "mpc.h"
* Minimally required library versions: gmp 4.3.2, mpfr 2.4.2
as math/mpcomplex.
Packaged by Marko Schuetz for pkgsrc-wip.
MPC is a C library for the arithmetic of complex numbers with
arbitrarily high precision and correct rounding of the result.
It is built upon and follows the same principles as MPFR.
