* A subtraction of two numbers of the same sign or addition of two
numbers of different signs can be rounded incorrectly (and the
ternary value can be incorrect) when one of the two inputs is
reused as the output (destination) and all these MPFR numbers
have exactly GMP_NUMB_BITS bits of precision (typically, 32 bits
on 32-bit machines, 64 bits on 64-bit machines).
* The mpfr_fma and mpfr_fms functions can behave incorrectly in case
of internal overflow or underflow.
* The result of the mpfr_sqr function can be rounded incorrectly
in a rare case near underflow when the destination has exactly
GMP_NUMB_BITS bits of precision (typically, 32 bits on 32-bit
machines, 64 bits on 64-bit machines) and the input has at most
GMP_NUMB_BITS bits of precision.
* The behavior and documentation of the mpfr_get_str function are
inconsistent concerning the minimum precision (this is related to
the change of the minimum precision from 2 to 1 in MPFR 4.0.0). The
get_str patch fixes this issue in the following way: the value 1
can now be provided for n (4th argument of mpfr_get_str); if n = 0,
then the number of significant digits in the output string can now
be 1, as already implied by the documentation (but the code was
increasing it to 2).
* The mpfr_cmp_q function can behave incorrectly when the rational
(mpq_t) number has a null denominator.
* The mpfr_inp_str and mpfr_out_str functions might behave
incorrectly when the stream is a null pointer: the stream is
replaced by stdin and stdout, respectively. This behavior is
useless, not documented (thus incorrect in case a null pointer
would have a special meaning), and not consistent with other
input/output functions.

%description
|
|
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).
