math/p5MathBigInt: update to 1.999837 (from 1.999827)
* Improve compatibility with older versions of the MathBigRat distribution.
* Reenable upgrading in Math::BigFloat>bdiv().
* Improvements to upgrading, downgrading, and rounding:
. Fix bug related to upgrading in Math::BigInt>brsft() in Perl <= 5.16.
. Fix Math::BigFloat>bpi().
. Improve as_int(), as_float(), and as_rat().
* Improve methods div_scale() and round_mode() so they work better with
subclasses. This fixes CPAN RT #125430.
* Make div_scale() accept a Math::Big(IntFloatRat) object as input. This
fixes CPAN RT #140599.
* Add new methods numerator(), denominator(), and fparts().
* Fix bug in to_ieee754(). Avoid that the significand overflows.

Update to 1.999825
Upstream changes:

* Make Math::BigInt accept integers regardless of whether they are written as
decimal, binary, octal, or hexadecimal integers or decimal, binary, octal, or
hexadecimal floating point number.
* When numeric constants are overloaded (with the ":constant" option) in
Math::BigInt, every numeric constant that represent an integer is converted
to an object regardless of how it is written. All finite nonintegers are
converted to a NaN.
* When numeric constants are overloaded (with the ":constant" option) in
Math::BigFloat, every numeric constant is converted to an object regardless
of how it is written.
* Add method from_dec() (cf. from_bin(), from_oct(), and from_hex()). It is
like new() except that it does not accept anything but a string representing a
finite decimal number.
1.999824 20210920
* Don't allow mixing math libraries. Use the first backend math library that is
successfully loaded, and ignore any further attempts at loading a different
backend library. This is a solution to the reoccurring problem of using
objects using different math libraries.
* Add missing documentation.
* Miscellaneous minor improvements.
1.999823 20210712
* Improve the handling of the backend libraries. Provide more useful warnings
and error messages. Update the documentation.
1.999822 20210709
* Make the from_hex(), from_oct(), and from_bin() methods consistent with
CORE::oct(), which does not require a leading "0" before the letter \
("x",
"o", or "b").
* Make the from_oct() and new() methods accept octal numbers with prefix
"0o", "0O", "o" (lowercase letter o), and \
"O" (capital letter O).
* Make the from_bin() and new() methods accept binary numbers with
prefix "0b", "0B", "b", and "B".
* Make the from_hex() and new() methods accept hexadecimal numbers with
prefix "0x", "0X", "x", and "X".
* Update test files to match with the above.
1.999821 20210706
* Make new() and from_hex() accept the "0X" prefix, not just the \
"0x" prefix,
but not accept just "X" or "x". Now, "0XFF" \
returns 255, not NaN.
* Make new() and from_bin() accept the "0B" prefix, not just the \
"0b" prefix, but
not accept just "B" or "b". Now, "0B1111" \
returns 255, not NaN.
* Make new() and from_oct() accept the "0o" and "0O" \
prefixes, but not accept
just "O" (capital letter O) or "o" (lowercase letter o). \
Now, "0o377" and
"0O377" return 255, not NaN. Also intepret floating point numbers with a
leading zero and a binary exponent as an octal number, so that "01.4p0"
returns 1.5, not NaN. There is still no ambiguety, since decimal floating
point numbers use "e" or "E" before the exponent, and \
binary and hexadecimal
floating point numbers use a "0b"/"0B" or \
"0x"/"0x" prefix, respectively.
1.999820 20210706
* Fix bug and improve error messages in Math::BigInt::import().
1.999819 20210702
* Add method btfac() (triple factorial) and bmfac() (multifactorial),
including tests and documentation.
* Add missing and correct erroneous documentation for bfac() (factorial)
and bdfac() (double factorial). Also correct handling of special cases
and add tests for these cases.
* Fix error in bsin() and bcos() causing them to hang indefinitely if the
invocand is +/inf.
* Make it possible for the end user to specify the base length used internally
in Math::BigInt::Calc.
