I need to printf a double, but i cant find a list fo the parameters anymore, anyone know the flag for double instead of single precision?

Try %f.
As opposed to scanf, printf has the same %f for both single and double, because single is translated to double before it's passed to printf.

I've always used %f for floats and %lf for doubles.

That'll possibly work in some compilers, but %lf in the Gnu C library (glibc) is using %lf for extended precision double (long double), so you would get it wrong on a Linux machine for example. Assuming it does work, it still does the same thing for %lf and %f, since both float and double are converted to double before printf even gets a sniff of the format string or the floating point value itself.Originally Posted by QuantumPete
I believe C99 makes %lf standard for long double.
