Storing floating numbers in binary format

[Arthoni]

Suggested by @crevoisier
Priority to be evaluated

Objective:

• avoid precision issues when dealing with cpp precision string output
• memory use efficiency

Cf discussion : https://stackoverflow.com/questions/2746380/float-to-binary-in-c

(could be extended to all OpenFLUID data types)

Question not totally decorrelated with the question of precision management in OpenFLUID (no point of keeping digits after the actual precision of the underlying value)
