Add float type for parameters & a few fixes (#95)

Browse Source 
* Fix not-relative include

throws if a include directory is not set.

* add forgotten defined() in environment checking '#elif's

* fix mis-spelled "config.j"

* Add float type support to Parameters

All 3 encodings supported.

* Using dptconvert functions to handle parameters handling
