Comparisons and Boolean Logic

Values can be compared for equality using the operator ==:

• • 3 == 3

• • 3 == 4

The special symbols True and False are used to denote truth values. Naturally, there are inequality comparisons as well:

• • 3 > 4

Inequalities can be chained:

• • 3 < 4 >= 2 != 1

Truth values can be negated using ! (logical not) and combined using && (logical and) and || (logical or):

• • !True

• • !False

• • 3 < 4 && 6 > 5

&& has higher precedence than ||, i.e. it binds stronger:

• • True && True || False && False

• • True && (True || False) && False
