Primitive type: boolean

A boolean is either @true@ or @false@.

In a script, numbers are implicitly converted to booleans, a non-zero number is @true@, 0 is @false@.

When converted to a number, @true@ becomes @1@ and @false@ becomes @0@.

The strings @"yes"@ and @"no"@ can also be converted to booleans.

--File syntax--
> boolean: true
> boolean: false

--Script syntax--
> true or false

The operators @or@, @and@ and @xor@ combine two booleans:
! @a@		@b@		<tt>a or b</tt>	<tt>a and b</tt>	<tt>a xor b</tt>
| @false@	@false@		@false@		@false@		@false@
| @false@	@true@		@true@		@false@		@true@
| @true@	@false@		@true@		@false@		@true@
| @true@	@true@		@true@		@true@		@false@
