## TCP-server-calculator Simple Node.js calculator handling 32bit unsigned integers using npm/net module to communicate with server via TCP connection, and send signal inputs via CLI and netcat on port 1010 - Features: - User session by client address/uid - Always producing positive results, including zero ### Example ```sh # Using netcat to produce results $/ echo 1/12 | nc localhost 1010 # should echo back with calculated result ``` ### Start To start the server just run: ```sh /$ node index # or /$ npm star ``` ### Stack Nodejs, net/sockets, client session ### How to interact Assume we are using netcat with the command `$/ echo {input} | nc localhost 1010` - Way to understand operations is ``, when concatenating... Operators can add before or after the ``, where initial input always starts with `` - Incomplete sequence kept concatenating, and held in memory, unless incorrect value entered _(session is cleared)_ - Successfully sequence handles ``, but before values are evaluated, you can keep concatenating. ```sh # example 1 20 # concat value with notice output -10 # produce: 10 # example 2 0.9- # concat ... 0.1 # produce unsigned integer value: 0 # example 3 10* # concat ... 5 # produce: 50 # example 4 0-1 # produce unsigned integer: 4294967295 # example 5 101 # concat ... /10 # produce: 10 # example 6, no division by 0 allowed 0/0 # produce: error # example 7, numbers must round above 0 0.1+ # concat ... 0.2 # produce: error # example 8, no spaces allowed 1 + 1 # produce: error # example 9, no alpha chars allowed hello world # produce: error # example 10, no division by 0 allowed 2 # concat ... /0 # produce: error # example 11, no modulo by 0 allowed 3 # concat ... %0 # produce: error # example 12, no more then allowed 3 # concat ... +3+ # concat ... 5 # produce: error ```
