DreamCalc Professional 是一个专为工程而设计的功能非常强大的科学计算器。 它允许你舍弃你的已存在的桌上型计算机。它可以在你的工作中扮演重要角色，程序界面清晰，非常方便使用。支持自然分数、广泛的三角计算，公制和英制之间的测量的转变，支持常数之间的变换，可选择的真实的命令模态，工程学和基数计算模态。

你是否也觉得市面上买到的工程用计算机价格昂贵，而且操作方式又复杂到你永远搞不清楚到底它有哪些功能？尤其是当你需要绘制一些图表协助你做判断时，市售的工程用计算机根本派不上用场；若要改用电脑统计软件进行分析，价格不但更昂贵而且操作更复杂。这个时候，你就需要 DreamCalc。DreamCalc 是专门设计用来取代市售工程用计算机的软件，它不但提供你工程用计算机该有的功能，还具有基本的统计图表绘制与分析能力。让你在难用的市售工程用计算机与高贵的专业统计软件之间，取得完美的平衡。
