void OnStart()
{
//--- 要转换的字符串
string str = "12345.54321";
//--- 将输入字符串作为实数转换为double型变量
double converted=StringToDouble(str);
//--- 在日志中显示精确到小数点后8位的结果数字
PrintFormat("The string '%s' is converted to the real number %.8f", str, converted);
/*
result:
The string '12345.54321' is converted to the real number 12345.54321000
