一個方便，快速，可靠，精確的工具，如果你需要找到標準函數的符號和數位衍生工具。衍生計算機 Real 45 以 C# 程式設計。所有計算都是以專有數據類型完成的。 計算器計算標準函數高訂單的導數（包括雙曲）。計算歷史記錄可以儲存到文本檔中或列印。 數位係數和值的計算精度為 45-54 位元。三角函數、指數函數、對數函數和反向函數。 獲得的符號公式可與計算機精度系列一起使用，可與圖形計算機 2D 參數、圖形計算器 2D Polar 和圖形計算機 2D 數位一起使用，用於繪圖圖形。還可以使用符號參數。例如，罪（a*x）=cos（b*x）=2*c。

終端使用者許可協定
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.
