浮点我可以，不行的是int型，负号不知道怎么处理方便。你找到方法了吗？
int main () { std::string str_dec = "2001, A Space Odyssey"; std::string str_hex = "40c3"; std::string str_bin = "-10010110001"; std::string str_auto = "0x7f"; std::string::size_type sz; // alias of size_t int i_dec = std::stoi (str_dec,&sz); int i_hex = st...

除了字符向量,您还可以使用 string 函数将数值、日期时间、持续时间和分类值转换为字符 串。 将数值数组转换为字符串数组。 X = [5 10 20 3.1416]; string(X) ans = 1x4 string array "5" "10" "20" "3.1416" 将日期时间值转换为字符串。 d = datetime('now'); string(d) ans = "03-Feb-2019 ...
