| Oct 16, 2013 at 1:46 | comment | added | Meh | @Hector I don't, I just load them using BinaryReadList using {Integer32, Real32}. Even if Mathematica uses 64-bit ints/floats, there is still a 6x overhead over C. | |
| Oct 16, 2013 at 1:23 | comment | added | Hector | How do you assert that an integer is represented by Integer32 in memory? As far as I can tell, you have no control on that. | |
| Oct 15, 2013 at 18:54 | comment | added | Meh | Hmm, the source is UNIX time, but Mathematica seems to convert them to Integer when I use the following function: Epoch[timestamp_] = AbsoluteTime[{1970}] + timestamp | |

| Oct 15, 2013 at 18:16 | comment | added | ssch | @halirutan at least it's almost unix time: unixTime[date___]:=AbsoluteTime[date] - AbsoluteTime[{1970, 1, 1}] | |
| Oct 15, 2013 at 18:04 | comment | added | halirutan | Mathematica's AbsoluteTime returns the Unix Time which is per default represented by a Real. Isn't it a possibility to use this? | |
