Scientific numbers

Code:

---

double var = 4894000000;
cout<<var;

---

This outputs 4.894e+009 for the value. How can I have it output 4894000000 instead?

I guess you could break the number up into smaller number such as 48940 and 00000 then you won't get the errors and in a console you can't tell the difference :)

So there's no other way to do it?

Try something like cout << setwidth(20) << dValue << endl;

Heresy:

You CAN use stdio in console mode programs.

PHP Code:

---

#include <stdio.h>
printf( "my big number = %f\n", var);

or
char t[80];
sprinf(t,"%f",var);
printf("%s\n",t);

or (non-ansi)

Cstring str;
str.format("%f",var);
cout << str;

cout is not ansi c. C++ supports ansi c, almost mostly.

The reason cout isn't ANSI C is because it's ANSI C++ :p

You can use stdio, but there's no point if you're using iostreams, which you should be in C++ programs.
