This is a Deno and Node JS/TS library for abbreviating numbers in the style Factorio does.
Numbers are abbreviated with a suffix for the order of magnitude (k, M, G) if they're great enough. One fraction digit is only shown if there are fewer than 2 digits and the number has a suffix or a fractional part.
