Usage

Run brsc from your terminal with the following options:

brsc [OPTIONS]

Options:

• -e, --expr <EXPR>
  Mathematical expression to evaluate (e.g., 2 + 2 * 3).

• -p, --precision <PRECISION>
  Set the precision for floating-point results.
  Default: 2.

• -q, --quiet
  Suppress all output except the result.

• -h, --help
  Show help information with a summary of available options.

• -V, --version
  Show the current version of the program.

Examples

Evaluate a simple expression:

brsc -e "2 + 2 * 3"

Set precision to 5 decimal places:

brsc -e "1 / 3" -p 5

Use quiet mode to only show the result:

brsc -e "2*2" -q
