dec2hex is a command-line Rust application that converts decimal numbers to hexadecimal. Whether you need to convert a single decimal number or process multiple numbers stored in a text file, dec2hex provides a reliable solution.

• Convert individual decimal numbers to hexadecimal.
• Process decimal numbers stored in a text file and output their hexadecimal representations.

To convert a single decimal number to hexadecimal, simply run the following command:

dec2hex <DECIMAL_NUMBER>

Replace <DECIMAL_NUMBER> with the decimal number you want to convert.

If you have decimal numbers stored in a text file and want to convert them to hexadecimal, use the following command:

dec2hex -f <INPUT_FILE> -o <OUTPUT_FILE>

Replace <INPUT_FILE> with the path to your input file containing decimal numbers, and <OUTPUT_FILE> with the desired name for the output file containing hexadecimal representations.

Please note that <OUTPUT_FILE> is an optional parameter and is not required by <INPUT_FILE>.

Currently there is a precompiled version for Windows only.

To build dec2hex, make sure you have a working installation of the Rust toolchain (typically installed via rustup) on your system. Then, clone this repository and navigate to its directory:

git clone https://github.com/toaaa/dec2hex.git
cd dec2hex

Next, build the application using Cargo:

cargo build --release

Once the build process is complete, you can find the executable file in the target/release directory. Alternatively, you can run it using:

cargo run --release
