You could use sprintf(target string, format string, double value);
But I'm sure there are other ways, too.

How do I get rid of the padding zeros when converting a double to a string. For example, this code prints out 134.560000.

int main(){ char str[20]; double x = 134.56; sprintf(str, "%f", x); cout << str << endl; return 0;} [edited by - LordG on March 21, 2002 11:53:03 PM]
