# 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[1]:=
 Out[1]=

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

 In[2]:=
 Out[2]=

### Applications (1)

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

 In[3]:=
 Out[3]=

### Properties and Relations (3)

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

 In[4]:=
 Out[4]=

BooleInverse is the inverse function of Boole:

 In[5]:=
 Out[5]=

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

 In[6]:=
 Out[6]=
 In[7]:=
 Out[7]=

### Possible Issues (2)

Only one argument is expected:

 In[8]:=
 Out[8]=
 In[9]:=
 Out[9]=

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

 In[10]:=
 Out[10]=
