Set Operations🔗

Table 2: Comparison operations
Operation	Meaning	HALCON operator	Alternative notation
`t1 < t2`	less than	`tuple_less`
`t1 > t2`	greater than	`tuple_greater`
`t1 <= t2`	less or equal	`tuple_less_equal`
`t1 >= t2`	greater of equal	`tuple_greater_equal`
`t1 == t2`	equal	`tuple_equal`	`t1 = t2` (legacy)
`t1 != t2`	not equal	`tuple_not_equal`	`t1 # t2` (legacy)

Example

1st Operand	Operation	2nd Operand	Result
`1`	`==`	`1.0`	`true`
`[]`	`==`	`[]`	`true`
`''`	`==`	`[]`	`false`
`[1,'2']`	`==`	`[1,2]`	`false`
`[1,2,3]`	`==`	`[1,2]`	`false`
`[4711,'Hugo']`	`==`	`[4711,'Hugo']`	`true`
`'Hugo'`	`==`	`'hugo'`	`false`
`2`	`>`	`1`	`true`
`2`	`>`	`1.0`	`true`

`[2,1]`	`>`	`[2,0]`	`true`
`true`	`>`	`false`	`true`
`'Hugo'`	`<`	`'hugo'`	`true`

Table 4: Elementwise comparison operations
Operation	Meaning	HALCON operator	Alternative notation
`t1 [<] t2`	less than	`tuple_less_elem`
`t1 [>] t2`	greater than	`tuple_greater_elem`
`t1 [<=] t2`	less or equal	`tuple_less_equal_elem`
`t1 [>=] t2`	greater of equal	`tuple_greater_equal_elem`
`t1 [==] t2`	equal	`tuple_equal_elem`	`t1 [=] t2` (legacy)
`t1 [!=] t2`	not equal	`tuple_not_equal_elem`	`t1 [#] t2` (legacy)
