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
