ABS() documentation is incorrect

[thearduinoguy]

https://www.arduino.cc/reference/en/language/functions/math/abs/

Page states:

Returns
x: if x is greater than or equal to 0.
-x: if x is less than 0.

This is incorrect. If x is less than zero it will return the positive value of X. The page seems to imply that ABS has no affect on any integer.

Please see arduino/Arduino#3338 (comment) for an explanation of why the documentation is correct.
