calct is a command-line calculator program available on Unix-like operating systems. It allows users to perform arbitrary precision arithmetic directly from the terminal. Unlike standard calculators that operate with fixed precision, calct can handle numbers of virtually any size, limited only by available memory.
The program is invoked by typing "calct" in the terminal. Users then enter mathematical expressions, which can
calct is particularly useful for tasks requiring high precision or when dealing with very large numbers that
