}

const inWords3 = convert('777.55', { format: 'intl' })
const inWords4 = convert(intlOptions) // pass as options as well.

console.log(convert('555'))  // five hundred fifty five
console.log(convert('1022')) // one thousand twenty two
console.log(convert('1,022')) // NaN
console.log(convert('66.123')) // sixty six.twelve
console.log(convert('99.11')) // ninety nine.eleven
console.log(convert('99.09')) // ninety nine; decimals lesser than .10 is rejected

console.log(convert(100000)) // one lakh
console.log(convert(100000, { format: 'int' })) // one hundred thousand

Note 1. Expect NaN when any invalid characters are present, eg: 10E55 2. Fractional part is corrected to two decimal places 3. Decimals from .00 to .09 is ignored.

Compatibility

Supports upto 15 digits for both indian and international systems on their integer part. A RangeError will be thrown for length beyond 15.

eg: calling convert with 999,999,999,999,999 + 1 will throw a range error

International system:

999,999,999,999,999 (1 quadrillion - 1)

Indian system:

99,99,99,99,99,99,999 (100 crore crore - 1)

Hacks

const amount = 0.99
const result = convert(`${amount}`) //  zero.ninety nine

const amount = '1,000.99'
const sanitized = amount.replace(/,/, '') //  1000.99

const amount = '123.123'
const [dollars, cents] = amount.split('.')
const result = `${convert(dollars)}.${convert(cents)}` // one hundred twenty threee.one hundred twenty three
