How does adding 0.01 improve rounding here? thanks.

It's stated in the description, not a kata issue.

Clarify that people not familiar with the gravitational force formula need to research it.

State that the forumula is not provided and that G is only a constant input.

The description only states that G = 6.67 × 10−11 N⋅kg−2⋅m2 which might be confused for the needed formula. In this case, N⋅kg−2⋅m2 might also be confused as inputs instead of the unit for G, and this in turn puts a question into how to get N and why is there only one kg input while the functions' arguments include the mass/weight of two objects!

This was more of a physics/research kata rather than a programming kata.
