RSC is a handwritten scientific calculator for turning an equation inside a string into a result. RSC is designed to be very lightweight and have as few dependencies as possible. It has the goal of just doing a single thing really well, and enabling anyone to extend it with more features.
RSC is also designed with the goal to not become bloated software. RSC will not receive frequent updates, but that does not mean it is old or unmaintained. That being said, RSC may still receive internal updates with relation to speed or resource usage.
The abbreviation can be interpreted in two majorly different ways:
- Rust Scientific Calculations library
- Rust Scientific Calculator
RSC is ~300 lines of code.
RSC computes instantaneously, even with debug builds.
RSC will not have any major changes to its syntax. It will remain to be consistent for a long time. It is up to forkers to make different tastes of RSC. It will also forever keep the same open-source permissions.
RSC is MIT licensed. RSC will always remain free to modify and use without attribution.

RSC can be run with the
ast flag and show the internal expression that was created by the parser. This is most commonly used for entertainment purposes 😛.
