发帖数: 52 | 1 现在学用mathcad写点算式.
发现mathcad 的数据只显示到3位有效数据.
比如输入:
a:=0.12345678901234
a=0.123
b:=a-0.123
b=4.567e-4
请问, 如何让mathcad 显示更多位的有效数据?
我需要15位有效数据显示.
另外请问, mathcad 里有Binary, Hex number and Conversion with Decimal?
谢谢. |

发帖数: 18 | 2 In Mathcad, just go to Insert>Component... and select "File Read or Write" in the dialog box.
Then, make sure the "Read from a file" radio button is highlighted on the next screen.
Under the next screen, select "Excel" from the File Type drop-down, choose your saved Excel file with the Browse... button.
Click Ok and Mathcad inserts a File Read component into your worksheet. See how the component is on the right side of the := assigment operator? Now all you do is tell Mathcad what variable to |

但把 .excel 文件改名为 .dat 文件, 就有error, 说数据不对什么的.
不知道我的做法对不对? 如何才能读入 Excel data?
还有, 我改了 .txt file 的数据, F9, mathcad 读入的数据好象没有自动更新?
谢谢. |

发帖数: 716 | 10 确实用MathCad最方便，而且很简单。前面zucchini说的都差不多了。
单位，磅要用lbf，这样所有相关单位MathCad就自己出来了。或者单独自己定义单位。
比如：pli = lbf/in，之类的。
MathCad做各种运算很方便，逻辑语句也很简单。随便网上或者Help里搜一下，很容易
上手。 |
