▸about anyamount

Formats a number the way the locale writes it — compact ("1.2M"), money ("€1,999.00"), units ("3.2 GB") — and reads a typed amount back into a number.

why

toFixed and hand-placed separators break outside en-US; numeral.js is 20 kB and English-first. anyamount is one call over the formatter the runtime already has — any currency, any sanctioned unit, bigint — plus parse() for the input field, the direction Intl never covered.

usage

anyamount(1234567)                                             // "1.2M"
anyamount(1999, { mode: "currency", currency: "EUR" })         // "€1,999.00"
anyamount(3.2, { mode: "unit", unit: "gigabyte" })             // "3.2 GB"
anyamount(1234, { compact: true })                             // "1.2K" — badges; compact: false never abbreviates
anyamount.range(10, 20, { mode: "currency", currency: "EUR" }) // "€10.00 – 20.00"
anyamount.parse("1.999,50", { locale: "de" })                  // 1999.5 — NaN when it is not a number
anyamount.symbol("USD")                                        // "$"

Money arithmetic, exchange rates, decimal precision — do the maths in minor units or a decimal library, then format the result here.
