• 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 print the output:

dc --expression='4 5 * 17 - p'

• Specify the number of decimal places to 7 (7 k), calculate 5 divided by -3 (5 _3 /) and print:

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 print result:

dc --expression='100 k 5 v 1 + 2 / p'
