• Start an interactive session:
   
  dc
   
• Execute a script:
   
  dc {{path/to/script.dc}}
   
• Calculate an expression with the specified scale:
   
  dc --expression='{{10}} k {{5 3 /}} p'
   
• Calculate 4 times 5 (4 5 *), subtract 17 (17 -), and [p]rint the output:
   
  dc --expression='4 5 * 17 - p'
   
• Set number of decimal places to 7 (7 k), calculate 5 divided by -3 (5 _3 /) and [p]rint:
   
  dc --expression='7 k 5 _3 / p'
   
• Calculate the golden ratio, phi: set number of decimal places to 100 (100 k), square root of 5 (5 v) plus 1 (1 +), divided by 2 (2 /), and [p]rint result:
   
  dc --expression='100 k 5 v 1 + 2 / p'
