The functions in this category allow to evaluate logical values; in Proteus, every value different from 0 is considered TRUE and 0 is considered FALSE, just like in 'C'.

AND([@]n1, [@]n2[, n3..])

logical AND; returns a number different from 0 if and only if all the values are different from 0

OR([@]n1, [@]n2[, n3..])

logical OR; returns a number different from 0 if and only if at least one value is different from 0

XOR([@]n1, [@]n2[, n3..])

logical exclusive OR; returns a number different from 0 if and only if at least one value is different from 0 and at least one value is 0

NOT([@]n)

logical NOT logico; returns a number different from 0 if and only if n is 0
