Remove redundant is_equal_approx_ratio method

is_equal_approx is able to handle values of any size, and is_equal_approx_ratio is no longer used in any exposed APIs, so we don't need is_equal_approx_ratio anymore. Also, add #ifdef MATH_CHECKS for a method that is only used when MATH_CHECKS is defined.
