How runways are called on take off?

LAX and DTW are similar. The LAX north complex is labeled 24R and 24L, even though the runway centerline is oriented 249.8 degrees. This eliminates any potential for pilot confusion, as if you are cleared for an approach to one of the 24s, it’s the north side, one of the 25s, the south side.

ATL is like this as well.
