分支语句 If expression1 Then expressions ElseIf expression2 Then expressions Else expression End If 注:VBA中等于号和赋值符号都是"=",但并不会冲突,只有在选择语句中“=”才表示是否相等 示例(交互型) 1.写好程序 2.设置动作 (View-->Toolbars-->Form Controls-->Toggle Design Mode-->Push Button)
算法提高 解二元一次方程组 时间限制:1.0s 内存限制:256.0MB 问题描述 给定一个二元一次方程组,形如: a * x + b * y = c; d * x + e * y = f; x,y代表未知数,a, b, c, d, e, f为参数. 求解x,y 输入格式 输入包含六个整数: a, b, c, d, e, f; 输出格式 输出为方程组的解,两个整数x, y. 样例输入 例: 3 7 41 2 1 9 样例输出 例: 2 5 数据规模和约定 0 <= a, b, c, d, e,
二元一次函数的实现 import cmathimport mathimport sys 这里导入cmath包是在后面用来处理复数的情况导入math使用来处理 平方 根号等的运算而导入sys的意义是为了比较0 ,在python中float的精度值不够,所以在计算复数时需要用到sys.float_info.epsilon def get_float(msg,allow_zero): x =None while x is None: try: x= fl
