I'm using "%0nl" formatting. This is formatting double values as fixed point (integer) number in most cases. But with very large or small numbers (e.g. 1e-16) it shows the floating point number (e.g. 1e-16). This is what I don't need.

I have checked the formatting function:

String FormatDouble(double d, int digits, int flags, int pad_exp)
{
	if(IsNull(d))
		return Null;

	double ad = fabs(d);
	bool is_exp = (flags & FD_EXP);
	if(!(flags & FD_FIX))
	{
		is_exp = ad && (ad <= 1e-15 || ad >= 1e15);
		if(flags & FD_REL)
		{
			double bd = ipow10(2 * digits);
			if(ad && (ad * bd <= 1 || ad >= bd))
				is_exp = true;
		}
	}
	if(is_exp)
		return FormatDoubleExp(d, digits, flags, pad_exp);
	else
		return FormatDoubleFix(d, digits, flags);
}

The problem is the "if(!(flags & FD_FIX))" block. I searched for FD_FIX in upp sources and I was unable to find any other references to it. Is something missing from parser or is this "if" block absolutely unneeded?
Or how can I enforce fixed point language based formatting?
