# Design notes for <cmath> test cases
#
# <cmath> must provide all math functions in the "std::" namespace. The
# global "::" namespace gets only the double form of those functions.
# Reference: https://en.cppreference.com/cpp/header/cmath
#
# C90 functions available in std:: since C++98.
# C99 functions (acosh, exp2, log2, round, trunc, hypot, fma, etc.)
# required in std:: since C++11.

# Regression test for 15209: log(int) must not be ambiguous. Before
# 15209, math_iso.h pulled logf/logl into :: via using-declarations,
# making log(int) ambiguous between float and double overloads.
# Integer arguments must resolve to the double overload unambiguously.
# This section also adds test cases representing problems seen when
# building third-party packages via pkgsrc.org including failures
# due to ambiguity with abs() in cstdlib.
