formating a number which is very very small will get NaN

[yiliang114]

import numeral from 'numeral';
console.log(
  'numeral',
  numeral('-0.0000000008851743227289433')
    .divide(0.01)
    .format('0.0'),
  numeral('-0.000000009433')
    .divide(0.01)
    .format('0.0'),
);

// numeral NaN 0.0

+1, I am facing the same issue when try to enter long integer (more than 22 digit.) Ex: 12345678901234567890123

[BenjaminVanRyseghem]

numbro(-0.00000000008851743227289433).format()
// "-8.851743227289433e-11"

numbro(12345678901234567890123).format()
// "1.2345678901234568e+22"

Maybe numbro is worth a try?
