Remi Beges 9fef43951b Replaced templates by float
*Since only valid template parameters were float and double, the whole
template aspect has been removed.
Double precision would only be used in extremely rare occasions
(applications needing high precision and slow performances), it is not
relevant to template the whole module for it.
