- Start `bc` in interactive mode using the standard math library:

`bc -l`

- Calculate the result of an expression:

`bc <<< "(1 + 2) * 2 ^ 2"`

- Calculate the result of an expression and force the number of decimal places to 10:

`bc <<< "scale=10; 5 / 3"`

- Calculate the result of an expression with sine and cosine using `mathlib`:

`bc -l <<< "s(1) + c(1)"`

Added a line about interactive usage with mathlib Usually `bc` isn't very useful if it doesn't return have floating point number where appropriate. e.g., 3/4 returns 0 when started with `-i` but for most users they would expect 0.75 to be returned so the argument `-l`does what the user would generally want. 2016-10-31 23:37:05 +00:00
