+# bc-7.0.3
+
+bc is an arbitrary-precision calculator language with a syntax similar to the C programming language. It supports interactive execution of statements, arbitrary precision numbers, and execution of scripts.
+
+## Features
+
+- Arbitrary precision arithmetic
+- Interactive calculator mode
+- Script execution capabilities
+- Standard mathematical functions
+- Support for variables and arrays
+- GNU bc extensions compatibility
+- Readline support for improved line editing
+
+## Usage
+
+bc can be used interactively:
+
+```bash
+bc
+scale=20
+1/3
+.33333333333333333333
+quit
+```
+
+Or for script execution:
+
+```bash
+bc -l script.bc
+```
+
+## Installation
+
+This package installs the bc calculator with readline support enabled, providing enhanced line editing features including command history, tab completion, and cursor movement.
+
+## Dependencies
+
+- readline library (for enhanced line editing)
+- GCC compiler (for building)
+- Make utility (for building)
+- Bash shell (for script execution)
