I want to write 45,000 with some numbers of significant figures.
It's really easy to write it with 2 significant figures: 45,000
5 significant figures is also easy: 45,000.
6 and up is also easy: 45,000.0
But how do I write it with 3 or 4 significant figures? I know it can be done with scientific notation, but I want to see if there's a way without it, since scientific notation can sometimes make the size of a number less visually obvious. Is this just a lexical gap with the notation, or is there a way to do it?
