Problem Generating ID
Hi All, I am generating a ID to use as primary key in my table with the follwing code. double regno = (double)System.currentTimeMillis() * Math.random(); I am getting the result in exponential form (5.797797409006919E11) . But I do not want the result in exponential form, but like for eg something like 57977974090069.3219 is there a way out? thanks Bopanna Power of Global Information Access... ..

Re: Problem Generating ID
Hi, why would you want to multiply the currentTimeMillis with math random ? The currentTimeMillis is unique onto itself? If you are concerned with multiple threads isn't is easier to append a thread id instead of risking two id that are the same because of the randomness introduced? greetz Hans At 03:26 PM 8/12/2003 +0530, N.B.Bopanna wrote: Hi All, I am generating a ID to use as primary key in my table with the follwing code. double regno = (double)System.currentTimeMillis() * Math.random(); I am getting the result in exponential form (5.797797409006919E11) .
