Convert to string notation required for auto precision

[ppKrauss]

It is possible to change

    if (typeof(latitude) === 'number' || typeof(longitude) === 'number') {
      throw new Error('string notation required for auto precision.');
    }

To something like

    if (typeof(latitude) === 'number') {
      latitude = parseFloat(latitude).toString();
    }
    if (typeof(longitude) === 'number') {
      longitude = parseFloat(longitude).toString();
    }

or direct enforce input.toString(), without checks or parseFloats.

I'm not sure if parseFloat returns correct precision as user want. Explicitly disable this indecisive behavior is preferred.

can you show an example? I not see the problem...
