Description
Description
Hello,I find when use the WriteValuePacked api to pack a float value, it will convert the float to uint.Due to the storage format of the float the convert value will bigger than 1 << 29,which can lead to the result of using 5 bytes to serialize the float,so can you tell me the reason why we convert the float to uint.
Reproduce Steps
Use the test runner to pack the float number.
Actual Outcome
Lead to the result of using 5 bytes to serialize the float.
Expected Outcome
Use less than 4 bytes to serialize the float.

Research direction
Start with the WriteValuePacked API and reproduce the float case using the test runner. Inspect the float-to-uint conversion and packed serialization behavior; done means the reason for the current byte count is established and a reproducible test verifies the expected serialized size.
