bc: Boolean Expressions

 
 3.4 Boolean Expressions
 =======================
 
 Boolean operations are also legal.  (POSIX 'bc' does NOT have boolean
 operations).  The result of all boolean operations are 0 and 1 (for
 false and true) as in relational expressions.  The boolean operators
 are:
 
 '!expr'
      The result is 1 if expr is 0.
 
 'expr && expr'
      The result is 1 if both expressions are non-zero.
 
 'expr || expr'
      The result is 1 if either expression is non-zero.
