Released Ver.1.0 of the Scientific Calculator App "RINPn"
2022/12/31 
We have released the first general release version (Ver.1.0) of the programmable scientific calculato app "RINPn". Explains the details.
RINEARN Graph 3D
» Details
RINEARN Graph 3D is an 3D graph software availale for plotting data from numerical files or spreadsheet software.
You can plot 3D graph by easy actions, e.g. you can plot data copied on a spreadsheet software by pasting it on the graph screen by rightclicking menu.
In addition, this software can render 3D graphs with realistic lighting/shading effects. It support you to recognize complicated shape of 3D graphs easily.
RINEARN Graph 3D is implemented in Java®, so it is also available as a 3D graph library for Java applications.

RINPn
» Details
RINPn is a scientific calculator software. The window of the RINPn is very simple, so you can use it very easily. You can input the entire of the expression, and you can execute the calculation by simply typing the Enter key.
The RINPn is equipped with the scripting engine of the Vnano, so you can define functions and variables in Clike simple programming language.
The RINPn is an open source software, and it is under development on the public repository on GitHub.
Exevalator
» Details
Exevalator is a compact library, which enables you to calculate values of numerical expressions stored in string variables, on Java/C#/C++/Rust programs.
Exevalator is implemented as single source file for each language, so you can embed it into your app very easily. In addition, Exevalator is released under the CC0, which is almost the same as the socalled "copyrightfree" (public domain).
Vnano
» Details
Vnano is a compact scripting engine for enabling Java® and Kotlin® applications to interpret script code (given as string data) on runtime and execute it.
As a scripting language, Vnano is a subset of the VCSSL which has a simple Clike syntax, so users who accustomed to Clike languages can use Vnano right away.
Vnano realizes the highspeed script processing by execute intermediate code on a VM of which architecture is a vector register machine. Its peak performance is about 400 MFLOPS (64bit) for scalar operations, and about 5 GFLOPS (64bit) for vector operations.
VCSSL
» Details
VCSSL is a programming language for lightweight computation, dataanalysis, visualization using 2D & 3D graphics, etc.
All parts of the runtime environment of the VCSSL (scripting engine, graphics engine, etc.) are implemented in Java, so the VCSSL is available on various type of OS for PC, e.g. Microsoft® Windows®, Linux, etc.
VCSSL has simple Clike syntax. If you are already useing other Clike programming languages ( C, C++, C#, Java, ... ), you can master VCSSL programming very easily.
