factorio-abbreviate-number

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.

| Number | Abbreviation | | ----------- | ------------ | | 1 | 1 | | 19 | 19 | | 199 | 199 | | 200 | 200 | | 1999 | 1.9k | | 2000 | 2.0k | | 19999 | 19k | | 20000 | 20k | | 199999 | 199k | | 1999999 | 1.9M | | 19999999 | 19M | | 199999999 | 199M | | 1999999999 | 1.9G | | 19999999999 | 19G | | 0.99 | 0.9 | | 1.9 | 1.9 | | 1.99 | 1.9 |
