-Changes in version 1.0:
- - 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
-
-Changes in version 0.9:
- - 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
- - mpc_exp: close to infinite loop for argument close to 0
- - mpc_sqrt: close to infinite loop for argument close to 1
- - mpc_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
-

Changes in version 0.8.1:

- - mpc_log: wrong ternary value in data file; masked by bug in mpfr-2.4.1
+ - acosh, asinh, atanh: swap of precisions between real and imaginary parts

Changes in version 0.7 ("Campanula uniflora"):
- New functions: mpc_pow, mpc_set_nan, mpc_swap
- Bug fixes:
- - mpc_log: along branch cut
- - mpc_norm: infinite loop in case of overflow
- - mpc_ui_div, mpc_div, mpc_fr_div: handling of division by 0 and
- infinities following the example code of the C99 standard
+ - log: along branch cut
+ - norm: infinite loop in case of overflow
+ - ui_div, div, fr_div: handling of division by 0 and infinities
+ following the example code of the C99 standard
- compilation with g++
- Makefile.vc updated (thanks to Mickael Gastineau)
- Minimal gmp version is 4.2
mpc_set_z_z and mpc_free_str
- New macro: MPC_SET_X_Y
- mpc_set_ui_fr removed
- - Default precision removed, as well as mpc_init and all mpc_init_set*
- combinations; use mpc_init2 or mpc_init3, followed by mpc_set, instead
- - mpc_exp, mpc_log, mpc_cos, mpc_sin, mpc_tan, mpc_cosh, mpc_sinh,
- mpc_tanh and mpc_sqrt return inexact value
+ - Default precision removed, as well as init and all init_set
+ combinations; use init2 and init3, followed by set, instead
+ - exp, log, cos, sin, tan, cosh, sinh, tanh and sqrt return
+ inexact value
- inp_str returns inexact value and the number of read characters
in an additional parameter
- Get default $CC and $CFLAGS from gmp.h (__GMP_CC / __GMP_CFLAGS,
