[Solved] Difference between 2 floats [closed]

by

[ad_1] The result is correct. Try to visualize it: Distance between -110 and 100 is the sum of distance between -110 and 0 (Mathf.Abs(-110 – 0) = 110) and distance between 100 and 0 (Mathf.Abs(100 – 0) = 100). That is: 110 + 100 = 210. Perhaps you have a different operation in mind? If … Read more
