Small weight being rounded to 0

[davist11]

Description Many of the products of the Commerce site we are building have very small weights. For example, one product I am looking at has a weight of 0.001 lbs. When I add that item to my cart and the boxes get packed to fetch the shipping rates, we are getting this error FedEx: Weight is missing or invalid.

I dove into the plugin a bit and tried to do some dumping to see what was going on. If I add a Craft::dd($packedBox); inside this foreach:

I get this output:

                )
                [*:width] => 0
                [*:length] => 0
                [*:depth] => 0

        [DVDoug\BoxPacker\PackedItemList:isSorted] => true
    )
    [*:itemWeight] => null
    [*:volumeUtilisation] => 0
)

So it appears like there is a weight value on the item. But if I do Craft::dd($weight); after the $weight variable is set, the value is 0. If I change the weight of the product to 0.5 lbs, then I correctly get shipping rates. Is there a specific minimum weight that Fedex expects? Let me know if there's any other info I can provide or if you want me to test other values. Thanks in advance!

Steps to reproduce

1. Add a small weight to a variant 0.001
2. Add that variant to your cart and checkout
3. See that no shipping options are available because the weight is 0

Additional info

Looks like an issue on our end. Should be fixed in 2.4.10
