Description

The class contains numbers "2.2251e-308" and "2.2204e-16".
The former is the "SAFE_MIN" defined in class "Precision".

The latter is documented as

2.2204e-16 is the machine epsilon for IEEE754

However, the "EPSILON" defined in class "Precision" is equal to "1.1102230246251565E-16" (i.e. half the above number). This requires clarification.
I would remove the seemingly incorrect comment (if we assume that the correct definition is in the comment for "EPSILON" in "Precision") and replace the hard-coded values with

2 * Precision.EPSILON

Do you agree?
