    使用LabVIEW编写的一个计算器程序。 计算器能完成的运算: 加减乘除,求平方,求立方,求自然对数,求以10为底的对数,求阶乘求正弦余弦正切值,符号取反 能完成的操作:角度与弧度的切换,退格,清零 缺点:由于显示使用的是数值类型,所以无法实现小数输入;只能进行十进制的计算,不支持其它进制,统计功能未实现-LabVIEW prepared to use a calculator program. Calculator to complete the calculations: addition and subtraction multiplication and division, and square, and cubic, and the natural logarithm, and to 10 for the end of the logarithm, and factorial values for sine cosine tangent, symbols take to complete the operation of the anti: the angle with radian switch, backspace, Clear shortcomings: As the show using a numerical type, it is not possible to realize a small number of input only for the calculation of the metric system, do not support the other band, did not achieve statistical functions

    K条路是在计算出一条最短路径后,继续计算几条次短路径。 多条路经可以为驾驶者提供多条路径选择,驾驶者可以根据自己的喜好选择路径。另外这些次短路径可以在最短路径阻塞时作为备选路经或应急路径使用。 计算中可以设定不同的条件来进行计算,如各路经共用路段多少,路径长度限制等。-K is the right route in the calculation of a shortest path to continue the calculation several times shorter path. Number of motorists passing by can provide multiple paths to choose and motorists can choose according to their own path. Also these times shorter path in the shortest possible path obstruction as an alternative path passing by or emergency use. Calculation of different conditions can be configured to carry out the calculation, such as the various sections by the number of shared, such as path length.
