# BooleInverse

Inverse of the Boole function

Contributed by: Daniel Sanchez (Wolfram Research)
 ResourceFunction["BooleInverse"][expr] yields True if expr is 1 and False if it is 0.

## Details and Options

ResourceFunction["BooleInverse"][expr] remains unchanged if expr is neither 1 nor 0.
ResourceFunction["BooleInverse"][expr] is effectively equivalent to Switch[expr,1,True,0,False].
ResourceFunction["BooleInverse"] is Listable.

## Examples

### Basic Examples (2)

Apply BooleInverse to a 0 and a 1:

 In:= Out= Convert a list of 1s and 0s to truth values:

 In:= Out= ### Applications (1)

BooleInverse is useful when testing a condition based on bit values:

 In:= Out= ### Properties and Relations (3)

BooleInverse[expr] is effectively equivalent to Switch[expr,1,True,0,False]:

 In:= Out= BooleInverse is the inverse function of Boole:

 In:= Out= BooleInverse deals with Rule in the same way that Boole does:

 In:= Out= In:= Out= ### Possible Issues (2)

Only one argument is expected:

 In:=  Out= In:=  Out= If the sole argument provided is neither 0 nor 1, the expression is not evaluated:

 In:= Out= Daniel Sanchez
