该计算器利用三个实变量计算实际函数的确定三元积分，利用三重锡辛四位一体方案。虽然对坦辛四合体的理论基础存在一些预防措施，但在实践中，该方案几乎是普遍的。数值的计算精度为 15-16 位。 所有计算结果都反映在"历史记录"富文本框中，该文本框可以保存在文件中或打印中。

1. You may install a copy of the Software on your personal computers. For each paid license you are given five available hardware profiles. One profile is considered as main and four as alternative. Each hardware profile is based on processor. You may install Software either on five computers at once, or install on one computer and keep four available profiles for future use, or in any other combination. Once activated a profiles becomes a used profile and number of available profiles decreases. A used profile cannot be replaced. For example, if a processor on your computer breaks down, you will have one main profile and three alternative profiles. If you have multiple operating systems on your computer, then you may install and activate the Software on each operating system under one profile. You may install and activate the Software on any virtual machine, but it can take an available profile, since virtual machines usually have different information for processor. If you have paid for a license, you may install and activate any past and future version of the Software. A paid license has no time limit. Activation of the Software requires internet connection. Once activated the Software does not require internet connection. 2. You may not reverse engineer, decompile, disassemble or otherwise attempt to discover the source code of the Software. 3. You may not alter or modify the Software or create a new installer for the Software.
