and* ( obj1 obj2 -- obj1/f )

Vocabulary

kernel

Inputs

obj1	a generalized boolean
obj2	a generalized boolean

Outputs

obj1/f

a generalized boolean

Word description

If both inputs are true, outputs obj1. Otherwise outputs f.

Notes

This word implements boolean and, so applying it to integers will not yield useful results (all integers have a true value). Bitwise and is the bitand word.

Examples

Usually only the boolean value of the result is used, however you can also explicitly rely on the behavior that if both inputs are true, the first is output:

USING: kernel prettyprint ; t f and* .
f

USING: kernel prettyprint ; t 7 and* .
t

USING: kernel prettyprint ; "hi" 12.0 and* .
"hi"
