SADI::Data::Float - A primitive SADI data type for float numbers

 use SADI::Data::Float;

 # create a SADI Float with initial value of -15.5
 my $data = SADI::Data::Float->new (value => -15.5);
 my $data = SADI::Data::Float->new (-15.5);

 # later change the value of this data object
 $data->value (79);
 print $data->value();
