Error: parsing: "1.5" cannot be parsed as Value given radix 10

Caused by:
    "1.5" cannot be parsed as Value given radix 10

also what is the easiest way to extract a numeric value with the new Value API? if the returned value is an integer, it seems like i need to do multiple .try_intos for each Value type when before i could simply do Context::<f64>::default().evaluate(&output) and always get an f64, even if the result was an integer
