推荐答案

您可以简单地将unsigned char值分配给double类型的变量，如下所示

unsigned char ch =``C'';
double d = ch;

如果您对使用c ++样式类型转换非常关注，请使用static_cast，如下所示

you can simply assign the unsigned char value to a variable of type double as shown below

unsigned char ch = ''C'';
double d = ch;

if you are so particular about using c++ style typecasting use static_cast as below

double d = static_cast<double>( ch );</double>

只需分配它:

Just assign it:

unsigned char u = 150;
double d = u;
