Is the module operator suppose to return negative values?

I though of using the module operator (%) to prevent angles from going onto negative values when using angle(), but it doesn't do it, even though it works like that in any calculator calculator and other programing languages (as far as I know).

example:

-90 % 360 should return 270, but in Construct 3 it return -90

%or mod has no standard behavior across programming languages. Some, like js, will will keep the sign of the original number, and some will wrap around 0 to the positive number. Which I think would be more useful.

Anyways since angle() gives an angle -180 to 180 you can convert it to the 0-360 range with

(a%360+360)%360

/// the second % is to get it back into the 0-360 range.

Or

A<0?360+A:A

Alternately you could use the angle conditions or the angleDiff expression to check your angles. They can be helpful especially when you have to deal with the 0-360 seam
