Origin Version (Select Help-->About Origin): 7.0 SR4
Operating System: win xp
I'm working with data that represents nanosecond time values from 0 up to 1 hour (in ns). Any ideas of how I can make it easier to deal with large integers (up to around 3600000000000) in Origin?
I don't need decimal precision, but enough so that I can count by nanosecond (ie 1,2,3...3600000000000...)...
Any suggestions?
If I can use these large integers in originC, is it possible to put values such as these in a visible worksheet? Or will the worksheet data always show up as doubles (without enough precision)?
Thanks,
- David Caplan |

Hi David,
I tried to change the option for the "Upper Threshold Poer"
(Tools:Options, Numeric Format tab) to the maximum, i.e., 14.
Then, I entered 3600000000000 and 3600000000001 to consequtive
cells in a worksheet column. Though I don't recall the exact
precision limit, it seems the worksheet cells can hold enough
digits in your case. (say, data1_b[2]-data1_b[1] returns the
value correctly 1).
Did you try?

Double Precision numbers can have 15 digits. Your numbers are only 13 digits. Therefore, ORIGEN can easily handle your numbers.
