What is the math symbol for rounding?

The math symbol for rounding is typically represented by a pair of brackets, such as ⌊x⌋ for rounding down (floor function) and ⌈x⌉ for rounding up (ceiling function). However, in general contexts, rounding to the nearest integer is often indicated simply by writing the number with a note to round it, rather than a specific symbol. There isn't a universally recognized single symbol for rounding in the way there is for operations like addition or multiplication.
