         When comparing two numbers, if the first number has magnitude less
         than 1e-5, we compare the two numbers directly and check whether
         they are equivalent within the specified precision. Otherwise, we
         compare the **ratio** of the second number to the first number and
         check whether it is equivalent to 1 within the specified precision.
