When nanoid is called with a fractional value, there were a number of undesirable effects:
- in browser and non-secure, the code infinite loops on while (size--)
- in node, the value of poolOffset becomes fractional, causing calls to nanoid to return zeroes until the pool is next filled
- if the first call in node is a fractional argument, the initial buffer allocation fails with an error
Version 3.3.8 and 5.0.9 are fixed.
