There are now nolibc definitions for the inverse cosine and inverse
sine.
More test points were added for acos, asin, and atan in the math_tests module.
This was done becuase the nolibc inverse trigonometric functions have
various branching conditions depending on the provided input value. Several
branches in these functions were neglected.
* C3_MATH feature
This feature allows the usage of noclib math files even when libc is in use.
If a nolibc symbol exists, it will be used in place of libc, otherwise
it will default to libc.
* Added MIT License notices to atan.c3
* Fix crt detection for arch linux
On archlinux, the crt is located directly in /usr/lib. Thus, the globbing done in find_linux_crt fails since it expects the crt to be in a subdirectory of /usr/lib. This patch fixes this issue.
* math_tests: rewrote test_atan()
Rewrote the atan test so that analagous checks are symmetrically
performed for all possible inputs: int, float, and double. The total
number of tests has increased while reducing the total amount of
code.
* math_tests: inverse trig and inverse hyperbolic trig
Tests were written for acos, acosh, asin, asinh, and atanh.
* math: cos macro missing values::promote_int
The cosine macro can't take an integer input without this fix. You can
see that some of the other macros, like the sine macro, have this.
* math_tests: trig and exponential
Wrote tests for the trigonometric macros as well as the
exponential macro. The hyperbolic trig macros use the exponential macro
rather than any LLVM instrinsics (for now at least, LLVM 19 has the proper
compiler intrinsics).
* math: float comparison
In the math module two macros were defined to assist in comparing
floating-point numbers for a given tolerance.
The trig, hyperbolic trig, and exponential tests in the math_tests module
were updated to use these macros instead of direct comparison.
* math: fix adjoint of Matrix2
Fix the adjoint of the Matrix2x2 implementation in the math module. This
also fixes the calculation of the inverse which depends on the adjoint.
* update release notes
Add gcd and lcm functions to calculate the greatest common divisor (gcd)
and the least common multiple (lcm) to the math module. This will also
work for BigInts that implements its own gcd/lcm.
Add inverse, conjugate, and equals functions to the Complex numbers. Add
an IMAGINARY constant to represent the imaginary unit. Also, add unit
tests for different types.
* sort: add is_sorted
Add is_sorted function to check whether a list is sorted or not. Sort
order (ascending or descending) will be detected by looking at the data.
Add tests.
* update the release notes
* refactor: use lambda
