#
# This exports the functionality of the NumPy core math library, aka npymath,
# which provides implementations of C99 math functions and macros for system
# with a C89 library (such as MSVC). npymath is available with NumPy >=1.3,
# although some functions will require later versions. The spacing function is
# not in C99, but comes from Fortran.
#
# On the Cython side, the npymath functions are available without the "npy_"
# prefix that they have in C, to make this is a drop-in replacement for
# libc.math. The same is true for the constants, where possible.
#
# See the NumPy documentation for linking instructions.
#
# Complex number support and NumPy 2.0 half-precision functions are currently
# not exported.
