brackets without a top, what do they mean?

Recommended Posts

What does the mathematical symbol that resembles brackets, [ or ], only *without* the line at the top. In other words, they look like a capital L and a reversed capital L. What do they mean? This type of thing is difficult to search on Google.

They refer to the floor and ceiling functions for real values, if there's no top it's the floor function, if there's no bottom it's the ceiling function.

These symbols mean "floor" and "ceiling" and cap the included expression to the nearest integer value. "Floor" to the next integer, smaller than the expression, "ceiling" to the next largest.
