float values should receive some validation

[kleetus]

Item class, setPrice, if $price is a float, we probably should not allow a float with an invalid value.

Example:

$item.setPrice(1.111111111111) will set this value as a float on item, which cannot be used, ultimately, to create an invoice.

What's an "invalid value"? Floating point numbers can't accurately store all numbers, for example 0.1.
The only solution imo is to throw an exception if a float is passed

I agree with @Dadibom.

I think we can throw InvalidArgumentException if the value is float type.
