float is emitted as object

[joheredi]

Describe the issue or request
When a spec has a float type it gets generated as object

model Foo {
   TestNonNullableFloat: float;
   TestNullableFloat: float | null;
   TestNonNullableFloat32: float32;
   TestNullableFloat32: float32 | null;
   TestNonNullableFloat64: float64;
   TestNullableFloat64: float64 | null;
}

Describe your ideas for solutions
Maybe generate the max possible representation which would be decimal

Hi @joheredi per typespec document, float is the base type of float32 and float64.
We did not handle this particular kind previously therefore it is emitted as object.
Since it is the base, from value's perspective, I think we should generate this type as double.
What do you think? @joheredi @m-nash

FYI we are doing the same for integer which is the base type of all integer types, and it is generated as long.
