dc: Parameters

 
 7 Parameters
 ************
 
 'dc' has three parameters that control its operation: the precision, the
 input radix, and the output radix.  The precision specifies the number
 of fraction digits to keep in the result of most arithmetic operations.
 The input radix controls the interpretation of numbers typed in; _all_
 numbers typed in use this radix.  The output radix is used for printing
 numbers.
 
    The input and output radices are separate parameters; you can make
 them unequal, which can be useful or confusing.  The input radix must be
 between 2 and 16 inclusive.  The output radix must be at least 2.  The
 precision must be zero or greater.  The precision is always measured in
 decimal digits, regardless of the current input or output radix.
 
 'i'
      Pops the value off the top of the stack and uses it to set the
      input radix.
 
 'o'
      Pops the value off the top of the stack and uses it to set the
      output radix.
 
 'k'
      Pops the value off the top of the stack and uses it to set the
      precision.
 
 'I'
      Pushes the current input radix on the stack.
 
 'O'
      Pushes the current output radix on the stack.
 
 'K'
      Pushes the current precision on the stack.
