and strings.

dec64_string.html is a description of the functions in dec64_string.c.

dec64_string_test.c is a test program.

dec64_math.c is a placeholder implementation of elementary functions. Many of these function are not accurate enough or fast enough. It should be replaced with a better implementation. The functions include

    acos    asin    atan    atan2    cos    exp      factorial
    log     raise   root    sin      sqrt   tan
and
    random  seed
