Annotation of OpenXM_contrib/gmp/mpfr/NEWS, Revision 1.1.1.1

1.1       ohara       1: Changes from version 2001 to version 2.0.1:
                      2: - new mathematical functions: acos, acosh, asin, asinh, atan, atanh, cosh,
                      3:   base-2 exponential and logarithm, base-10 logarithm, expm1, factorial,
                      4:   pow, pow_si, pow_ui, sinh, tan, tanh, ui_pow, ui_pow_ui
                      5: - other new functions: mpfr_const_euler, mpfr_dim, mpfr_fma, mpfr_hypot,
                      6:   mpfr_min, mpfr_max, mpfr_rint, mpfr_set_inf, mpfr_set_nan
                      7: - new operations with mpz or mpz: mpfr_{add,sub,mul,div}_[zq]
                      8: - new predicates: mpfr_inf_p, mpfr_nan_p, mpfr_number_p, mpfr_isinteger,
                      9: - add mechanism to set/check exponent range (overflow, underflow), partially
                     10:   implemented in the mpfr functions.
                     11: - efficiency: mpfr_div is now faster when the divisor has a few limbs
                     12: - rounding: now mpfr_pow implements exact rouding, and most functions return a
                     13:   ternary value indicating the position of the returned value wrt the exact one
                     14:   (thus the return value is now 'int' instead of 'void')
                     15: - complete rewrite of the configuration files
                     16: - mpfr_get_d, mpfr_{add,sub}_one_ulp now get a rounding mode as 2nd argument
                     17: - some function names did change: mpz_set_fr is now mpfr_get_z_exp,
                     18:   mpfr_print_raw is now mpfr_print_binary.
                     19:
                     20: Changes from version 1.0 to version 2001:
                     21: - the default installation does not provide any more access to machine
                     22:   rounding mode, and as a consequence does not compare MPFR results with
                     23:   precision=53 to machine results. Add option -DTEST if you want to have
                     24:   access to machine rounding mode, and to check MPFR results against.
                     25: - the MPFR files do not need <math.h> any more
                     26: - the header file <mpfr.h> was split into <mpfr.h> for exported functions
                     27:   and <mpfr-impl.h> for internal functions. The user should not use functions
                     28:   or macros from <mpfr-impl.h>, since those may change in further releases.
                     29: - <mpfr.h> was modified in order to make easy a C++ interface
                     30: - MPFR now deals with infinities (+infinity and -infinity) and NaN
                     31: - the missing function mpfr_swap is now available
                     32: - mpfr_zeta was removed (was incomplete)
                     33: - mpfr_init and mpfr_init2 now initialize the corresponding variable to 0
                     34:   (like in other initialization functions from GNU MP)
                     35: - in case memory allocation fails, an error message is output
                     36: - several bugs of version 1.0 were fixed
                     37:
                     38: Changes from version 0.4 to version 1.0:
                     39:
                     40: - Version 1.0 now uses a standard configure/make installation.
                     41: - Version 1.0 implements all functions that are available in the MPF class
                     42:   from GMP 3.1 (except mpf_swap) and a header file mpf2mpfr.h is included in
                     43:   the distribution for easy change from MPF to MPFR.
                     44: - Version 1.0 implements new elementary functions: mpfr_sincos
                     45: - Some functions and macros have been renamed: mpfr_log2 is now
                     46:   mpfr_const_log2, mpfr_pi is now mpfr_const_pi, SIGN is now MPFR_SIGN.
                     47: - Version 1.0 uses faster algorithms for mpfr_exp, mpfr_const_pi,
                     48:   mpfr_const_log2. Compare the timings from version 1.0 and version 0.4.
                     49: - Version 1.0 corrects some bugs of version 0.4.
                     50: - The precision of MPFR variables is now named mpfr_prec, which makes it
                     51:   easier to change it, to say unsigned long long. Same for the rounding mode
                     52:   which is called mp_rnd_t.
                     53:
                     54: You'll find other news concerning the MPFR library on the web
