bc: Relational Expressions

 
 3.3 Relational Expressions
 ==========================
 
 Relational expressions are a special kind of expression that always
 evaluate to 0 or 1, 0 if the relation is false and 1 if the relation is
 true.  These may appear in any legal expression.  (POSIX 'bc' requires
 that relational expressions are used only in 'if', 'while', and 'for'
 statements and that only one relational test may be done in them.)  The
 relational operators are
 
 'expr1 < expr2'
      The result is 1 if expr1 is strictly less than expr2.
 
 'expr1 <= expr2'
      The result is 1 if expr1 is less than or equal to expr2.
 
 'expr1 > expr2'
      The result is 1 if expr1 is strictly greater than expr2.
 
 'expr1 >= expr2'
      The result is 1 if expr1 is greater than or equal to expr2.
 
 'expr1 == expr2'
      The result is 1 if expr1 is equal to expr2.
 
 'expr1 != expr2'
      The result is 1 if expr1 is not equal to expr2.
