Functions

Go	TypeScript	Returns
`rupiah.Format(a, opts)`	`rupiah.format(n, opts?)`	`Rp1.500.000,50`
`rupiah.Parse(s)`	`rupiah.parse(s)`	The amount (Go: `Amount` in sen, TypeScript: number in rupiah)
`rupiah.Valid(s)`	`rupiah.isValid(s)`	Whether `s` parses
`rupiah.Terbilang(a)`	`rupiah.terbilang(n)`	`satu juta lima ratus ribu rupiah lima puluh sen`

Amounts

Go uses rupiah.Amount, an int64 in sen, so arithmetic is exact: 150_000 * rupiah.Rupiah + 50 * rupiah.Sen.
TypeScript uses a number in rupiah. Amounts with sen are limited to below 10 trillion (MAX_SEN_AMOUNT) so they stay exact. Whole amounts go up to 999 trillion (MAX_AMOUNT).

Format options

Go `Options`	TypeScript	Effect
`Decimals`	`decimals`	Always print sen: `Rp2.000.000,00`
`OmitSymbol`	`symbol: false`	No `Rp` prefix

Without Decimals, sen is printed only when it is not zero. Negative amounts are formatted as -Rp1.000.

Parsing

Parse accepts what people write in Indonesia: an optional Rp, Rp. or IDR prefix, dots as thousands separators, a comma before sen, and a trailing ,-. Rp 25.000,-, IDR 1.500.000,50 and 25000 all parse. Input is limited to 64 characters.

Errors

length, charset, format (misplaced separators, more than two sen digits), range (larger than the supported amount).
