4.10 Logical Operator

The usage of the three logical operators (conjunction, disjunction, exclusive or) is shown in Table 4.7. In addition the results of the combination of boolean values (1:true, 0:false) are shown in Table 4.8,Table 4.9 and Table 4.10.

Table 4.7: Summary of logical operators

Description	Format	Example
Conjunction	$bool_1 \& \& bool_2$	`"abc"=="abc" && "xyz"=="abc" (0b0)`
Disjunction	$bool_1 \|\| bool_2$	`"abc"=="abc" \|\| "xyz"=="abc" (0b1)`
Exclusive or	$bool_1$ $\^{}$ $\^{}$ $bool_2$	`"abc"=="abc" ^^ "xyz"=="abc" (0b1)`

The results of the examples are shown in parentheses (the content is shown using constant numbers).
