### 6.4 Removed Functions ¶

Functions `mpfr_random` and `mpfr_random2` have been removed in MPFR 3.0 (this only affects old code built against MPFR 3.0 or later). (The function `mpfr_random` had been deprecated since at least MPFR 2.2.0, and `mpfr_random2` since MPFR 2.4.0.)

Macros `mpfr_add_one_ulp` and `mpfr_sub_one_ulp` have been removed in MPFR 4.0. They were no longer documented since MPFR 2.1.0 and were announced as deprecated since MPFR 3.1.0.

Function `mpfr_grandom` is marked as deprecated in MPFR 4.0. It will be removed in a future release.
