+// for various platforms. 2^-21 (approx. 4.76e-07) seems to be as accurate as we can get.
+//
+// The tests themselves will take PAL_EPSILON and adjust it according to the expected result
+// so that the delta used for comparison will compare the most significant digits and ignore
+// any digits that are outside the double precision range (6-9 digits).
+
+// For example, a test with an expect result in the format of 0.xxxxxxxxx will use PAL_EPSILON
+// for the variance, while an expected result in the format of 0.0xxxxxxxxx will use
+// PAL_EPSILON / 10 and and expected result in the format of x.xxxxxx will use PAL_EPSILON * 10.
