Excuse me if I wasn't much clear: local_y is declared as a pointer to float and
allocated through a calloc(2,sizeof(float));
The strange fact is that its values are printed correctly if it is passed as a
parameter to a function,and are wrong if they are printed directly!
Note that that each position is initialized calling  (float)[uniformDblRand
getDoubleWithMin:3.0L withMax:6.0L], so
the two values 452.150452 and 0.00000 are clearly wrong!
