* BOOST_MATH_EXPORT on autodiff (make_fvar, make_ftuple, promote,
real_cast), finite differences, lanczos smoothing, the complex
inverse trigonometric functions, quaternion and octonion including
their macro generated operator sets, and the boost/math_fwd.hpp
forward declarations
* Fixes a pre-existing ambiguity: autodiff's fully qualified
differentiation::detail::fvar references are ambiguous whenever
finite_difference.hpp is visible in the same translation unit, so
they now name the autodiff_v1 inline namespace explicitly
* Adds differentiation, complex.hpp, quaternion.hpp and octonion.hpp
to the module interface unit (finite_difference and lanczos_smoothing
precede autodiff by necessity)
* Module test harness gains quaternion_constexpr_test and
octonion_test_simple; both tests now include what they use
* BOOST_MATH_EXPORT on the statistics free functions (univariate,
bivariate, tests, regression, signal) and the optimization
algorithms, parameter structs and constraint/convergence policies
* BOOST_MATH_TEST_EXPORT on the optimization detail helpers the
differential evolution test exercises directly
* Adds the statistics and optimization headers to the module interface
unit; cma_es is excluded because it requires Eigen
* test_functions_for_optimization.hpp resolves constants through the
import in module mode
* Module test harness gains test_runs_test, linear_regression_test,
ljung_box_test, differential_evolution_test and random_search_test
* BOOST_MATH_EXPORT on the integrator class templates, trapezoidal and
the wavelet transform, plus the interpolator class templates and their
stream operators
* Adds the quadrature and interpolator headers to the module interface
unit (cardinal_trigonometric and the deprecated boost::math namespace
shims stay textual only)
* Module test harness gains git_issue_898,
cardinal_quadratic_b_spline_test and whittaker_shannon_test
* BOOST_MATH_EXPORT on the root finders, minima, polynomial and its
operators, rational/polynomial evaluators, series and continued
fraction machinery, recurrences, norms, condition numbers, color maps,
expansions, agm and toms748
* Adds the curated tools headers to the module interface unit
* Module test harness gains git_issue_1139, cubic_roots_test and
quartic_roots_test
* BOOST_MATH_EXPORT on the constexpr cmath function set
* Adds ccmath/ccmath.hpp to the module interface unit
* Module test harness gains ccmath_isinf_test and ccmath_isnan_test
* BOOST_MATH_EXPORT on the 38 distribution class templates (fwd.hpp and
definition sites), every non-member accessor overload, the convenience
typedefs, the complement machinery and find_location/find_scale
* distributions/fwd.hpp now includes tools/config.hpp so the export
macro is always defined
* Adds distributions.hpp to the module interface unit
* Module test harness gains git_issue_1294, git_issue_800,
git_issue_1120 and scipy_issue_17146
* BOOST_MATH_EXPORT on the public declarations in math_fwd.hpp,
round_fwd.hpp, unchecked_factorial.hpp, unchecked_bernoulli.hpp and
every special function header (declaration and definition sites)
* Adds special_functions.hpp to the module interface unit
* rsqrt.hpp, jacobi.hpp and cardinal_b_spline.hpp now include
tools/config.hpp so the export macro is always defined
* math_unit_test.hpp resolves math entities through the import in
module mode
* Module test harness gains test_digamma_simple, test_expm1_simple,
test_log1p_simple, git_issue_1194 and git_issue_1255
Mechanical sweep wrapping every standard library include in
#ifndef BOOST_MATH_BUILD_MODULE so the module interface unit can provide
them through the global module fragment or import std. Also converts the
static constexpr color map data tables to BOOST_MATH_INLINE_CONSTEXPR for
module linkage. No change in any existing configuration; validated against
the full compile_test suite and the module build.
Adds gated C++20 named module support (module boost.math), inert unless
BOOST_MATH_BUILD_MODULE is defined:
* BOOST_MATH_EXPORT / BOOST_MATH_TEST_EXPORT macro block in tools/config.hpp
* module/math.cxx interface unit covering constants and policies
* module/CMakeLists.txt test harness requiring import std
* module/quick_test.cpp smoke test and module/Jamfile for b2
* test/CMakeLists.txt branch for -DBOOST_MATH_BUILD_MODULE=ON
* cmake-module-test CI job (clang-20 + libc++ + CMake 4.4.0)
* Export annotations for constants, policies, error handling, and the
tools support headers they pull in
* std includes in those headers guarded for module builds
* Namespace scope static constexpr variables converted to
BOOST_MATH_INLINE_CONSTEXPR (float_constants and friends,
max_string_digits) for module linkage
The degree of freedom finders can call the quantile with arguments which result in an infinite result, as far as our root finders are concerned, any large value as a result will do, but we need to not allow an exception to escape or the root finder terminates.
