|
|
|
- Start an interactive session:
|
|
|
|
`bc`
|
|
|
|
- Start an interactive session with the standard math library enabled:
|
|
|
|
`bc {{[-i|--interactive]}} {{[-l|--mathlib]}}`
|
|
|
|
- Calculate an expression:
|
|
|
|
`echo '{{5 / 3}}' | bc`
|
|
|
|
- Execute a script:
|
|
|
|
`bc {{path/to/script.bc}}`
|
|
|
|
- Calculate an expression with the specified scale:
|
|
|
|
`echo 'scale = {{10}}; {{5 / 3}}' | bc`
|
|
|
|
- Calculate a sine/cosine/arctangent/natural logarithm/exponential function using `mathlib`:
|
|
|
|
`echo '{{s|c|a|l|e}}({{1}})' | bc {{[-l|--mathlib]}}`
|
|
|
|
- Execute an inline factorial script:
|
|
|
|
`echo "define factorial(n) { if (n <= 1) return 1; return n*factorial(n-1); }; factorial({{10}})" | bc`
