Question about aJsonStream::printFloat

Hello,

I would like to know why aJsonStream::printFloat is not written simply as:

```
int aJsonStream::printFloat(aJsonObject *item)
{
  if (item != NULL)
    {
      double d = item->valuefloat;
      this->print(d, FLOAT_PRECISION);
   }
  //printing nothing is ok
  return 0;
}
```

Thanks in advance,

Nicolas
