    #import <Cocoa/Cocoa.h>
    #include <iostream>
    #include <sstream>
    #include <iomanip>
    #include <string.h>
    using namespace std;
    int main(int argc, char *argv[])
    {
        double d = 0.00000000000000000000001;
        stringstream ss;
        string s;
        ss<<fixed<<setprecision(1000)<<d;
        ss>>s;

        const char * ptr=s.c_str();
        NSString * nss=[NSString stringWithCString:ptr];
        NSLog(@"%@\n",nss);
        return NSApplicationMain(argc,  (const char **) argv);
    }


要把附檔名從.m改成.mm
setprecision() 看你想要變成幾位數...
