Float Size

[Technocrat]

Maybe I am tired or something. But I cant figure out how to do this easily. If I have a float how can I tell its whole number size or places.

Example:
9 = 1 place
93 = 2 places
934 = 3 places
9349 = 4 places
93490 = 5 places
and so on.

I figure I could convert it to a string then get the length, but that seems like to much work. Anyone got a better idea?

Well I got this, unless someone has something better;

	float f = 1235.00;
	float t = f;
	int i = 0;
	while(t >= 1)
	{
		t = t / 10;
		i++;
	}

Don't know if taking the log to base 10 is better.
