REBOL 3 Functions: and

and value1 value2

Returns the first value ANDed with the second.

Arguments:

value1 [logic! integer! char! tuple! binary! bitset! typeset! datatype!]

value2 [logic! integer! char! tuple! binary! bitset! typeset! datatype!]

Description

For logic! values, both values must be true to return true, otherwise a false is returned. AND is an infix operator.

print true and true
true

print true and false
false

print (10 < 20) and (20 > 15)
true

Programming style

It's usually better to use all for anding conditional logic, such as the example above.

if all [10 < 20 20 > 15] ...

For integer!, tuple!, binary!, and other datatypes, each bit is separately anded.

print 123 and 1
1

print 1.2.3.4 and 255.0.255.0
1.0.3.0
