If you asked for 64 bits, you'd get it, if you asked for datetime128 -- what would you get??? a 128 bit integer? or an Exception, because there is no 128bit datetime dtype. But I think this is the same problem with any dtype -- if you ask for a precision that doesn't exist, you're going to get an error. Is there a more detailed description of the proposed feature anywhere? Do you specify a dtype as a precision? or jsut the precision, and let the dtype figure it out for itself, i.e.: precision=64 would give you a float64 if the passed in array was a float type, but a int64 if the passed in array was an int type, or a uint64 if the passed in array was a unsigned int type, etc..... But in the end, I wonder about the use case. I generaly use asarray one of two ways: Without a dtype -- to simple make sure I've got an ndarray of SOME dtype. or With a dtype - because I really care about the dtype -- usually because I need to pass it on to C code or something. I don't think I'd ever need at least some precision, but not care if I got more than that.... -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov
