Since C99, `FLT_EVAL_METHOD` should be left for the compiler/libc to define. Its redefinition breaks compilation with picolibc as the target's libc, since it defines said symbol in math.h before the libm define is evaluated by the compiler. In its place, there is a check to make sure floating point type sizes are what are expected to be, triggering a compilation error if those assumptions are no longer valid.

This directory contains source code for the standard double-precision math functions. The files lgamma.c, log10.c and tanh.c are too small to have a meaningful copyright or license. The file copysign.c contains a double version of the float copysignf provided in libm/math.c for use in DEBUG builds where the standard library copy is not available.
