[SciPy-user] histogramdd question

[Chris Lee]

Thanks David,

That makes sense. How difficult would it be to put in an optional 
parameter to only use integers?
In some sense this doesn't matter too much since I can (in pathological 
cases) end up with a 700 GB histogram but normally It clocks in between 
0.8-2 GB. In the end type casting isn't going to stop me from grabbing 
all the memory I can.
