(a..b)	{x | a < x < b}	open(C, C)
[a..b]	{x | a <= x <= b}	closed(C, C)
[a..b)	{x | a <= x < b}	closedOpen(C, C)
(a..b]	{x | a < x <= b}	openClosed(C, C)
(a..+∞)	{x | x > a}	greaterThan(C)
[a..+∞)	{x | x >= a}	atLeast(C)
(-∞..b)	{x | x < b}	lessThan(C)
(-∞..b]	{x | x <= b}	atMost(C)
(-∞..+∞)	all values	all()
