I just replaced this line with the below code and the test fails suggesting that the operation is giving no errors for field4 . Is this expected behaviour or am I missing something?
val, err = hmap.incrementFloatValue("field4", 1.0)
val, err = hmap.incrementFloatValue("field4", math.MaxFloat64)

Yes very counter intuitive, but this is the expected behavior in Go.
