6.2 Added Functions

We give here in alphabetical order the functions that were added after MPFR 2.2, and in which MPFR version.

• mpfr_add_d in MPFR 2.4.
• mpfr_ai in MPFR 3.0 (incomplete, experimental).
• mpfr_asprintf in MPFR 2.4.
• mpfr_buildopt_decimal_p and mpfr_buildopt_tls_p in MPFR 3.0.
• mpfr_buildopt_gmpinternals_p and mpfr_buildopt_tune_case in MPFR 3.1.
• mpfr_clear_divby0 in MPFR 3.1 (new divide-by-zero exception).
• mpfr_copysign in MPFR 2.3. Note: MPFR 2.2 had a mpfr_copysign function that was available, but not documented, and with a slight difference in the semantics (when the second input operand is a NaN).
• mpfr_custom_get_significand in MPFR 3.0. This function was named mpfr_custom_get_mantissa in previous versions; mpfr_custom_get_mantissa is still available via a macro in mpfr.h:

  #define mpfr_custom_get_mantissa mpfr_custom_get_significand
  

  Thus code that needs to work with both MPFR 2.x and MPFR 3.x should use mpfr_custom_get_mantissa.

• mpfr_d_div and mpfr_d_sub in MPFR 2.4.
• mpfr_digamma in MPFR 3.0.
• mpfr_divby0_p in MPFR 3.1 (new divide-by-zero exception).
• mpfr_div_d in MPFR 2.4.
• mpfr_fmod in MPFR 2.4.
• mpfr_fms in MPFR 2.3.
• mpfr_fprintf in MPFR 2.4.
• mpfr_frexp in MPFR 3.1.
• mpfr_get_flt in MPFR 3.0.
• mpfr_get_patches in MPFR 2.3.
• mpfr_get_z_2exp in MPFR 3.0. This function was named mpfr_get_z_exp in previous versions; mpfr_get_z_exp is still available via a macro in mpfr.h:

  #define mpfr_get_z_exp mpfr_get_z_2exp
  

  Thus code that needs to work with both MPFR 2.x and MPFR 3.x should use mpfr_get_z_exp.

• mpfr_grandom in MPFR 3.1.
• mpfr_j0, mpfr_j1 and mpfr_jn in MPFR 2.3.
• mpfr_lgamma in MPFR 2.3.
• mpfr_li2 in MPFR 2.4.
• mpfr_min_prec in MPFR 3.0.
• mpfr_modf in MPFR 2.4.
• mpfr_mul_d in MPFR 2.4.
• mpfr_printf in MPFR 2.4.
• mpfr_rec_sqrt in MPFR 2.4.
• mpfr_regular_p in MPFR 3.0.
• mpfr_remainder and mpfr_remquo in MPFR 2.3.
• mpfr_set_divby0 in MPFR 3.1 (new divide-by-zero exception).
• mpfr_set_flt in MPFR 3.0.
• mpfr_set_z_2exp in MPFR 3.0.
• mpfr_set_zero in MPFR 3.0.
• mpfr_setsign in MPFR 2.3.
• mpfr_signbit in MPFR 2.3.
• mpfr_sinh_cosh in MPFR 2.4.
• mpfr_snprintf and mpfr_sprintf in MPFR 2.4.
• mpfr_sub_d in MPFR 2.4.
• mpfr_urandom in MPFR 3.0.
• mpfr_vasprintf, mpfr_vfprintf, mpfr_vprintf, mpfr_vsprintf and mpfr_vsnprintf in MPFR 2.4.
• mpfr_y0, mpfr_y1 and mpfr_yn in MPFR 2.3.
• mpfr_z_sub in MPFR 3.1.
