The MPFR multiple-precision floating-point library
The MPFR library is a C library for multiple-precision floating-point
computations with exact rounding (also called correct rounding). It is
based on the GMP multiple-precision library.
The main goal of MPFR is to provide a library for multiple-precision
floating-point computation which is both efficient and has a
well-defined semantics. It copies the good ideas from the ANSI/IEEE-754
standard for double-precision floating-point arithmetic (53-bit
mantissa).

- Update to mpfr 4.1.0
* New function mpfr_get_str_ndigits about conversion to a string of digits.
* New function mpfr_dot for the dot product (incomplete, experimental).
* New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available only
when MPFR has been built with decimal float support).
* New function mpfr_cmpabs_ui.
* New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
* The mpfr_out_str function now accepts bases from -2 to -36, in order to
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
assertion failure, as with other invalid bases).
* Shared caches: cleanup; really detect lock failures (abort in this case).
* The behavior of the formatted output functions (mpfr_printf, etc.) with
an empty precision field has improved: trailing zeros are kept in a way
similar to the formatted output functions from C.
* Improved mpfr_add and mpfr_sub when all operands have a precision equal to
twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
* Optimized the tuning parameters for various architectures.
* Improved test coverage to 98.6% of code for x86_64.
* Bug fixes.
* MPFR manual: corrected/completed the mpfr_get_str description in order to
follow the historical behavior and GMP's mpf_get_str function.
- Remove mpfr-4.0.2-p6.patch and floating-point-format-no-lto.patch
