I am very happy to hear about the length of the numpy arrays other users
uses because I uses these day pow(2,22) = len(array) = 4194304 and I
seriously ask me questions about python memory managment. My program uses
hundreds Megs of RAM. My question is how many memory uses a
Numeric.array(pow(2,22), Numeric.Float) is it much more than pow(2,24)
bytes ?

A bientot,
