RND() is a random number generator. * It is the first random number generator app for Windows Phones that prevents duplicates. * When using the prevent duplicates feature, It is the first cell phone app (Windows, Android, iPhone) that can generate all of the random number combination at once. Update 1.1 - Per request added the ability to copy results to the clipboard. RND() can generate up to 2,500 random numbers per session with values ranging from 0 to 9,999,999,999 when using the zero decimal places setting, or from 0.000 to 999,999.000 when using the 3 decimal place setting. If the total number of unique combinations is equal to or less than 2,500. You can optionally use RND() to Prevent Duplicates numbers from being returned more than once. Using RND() you can generate 1, 10, or 100 random numbers at a time. When using the Prevent Duplicate feature, the option to generate 100 random numbers is replaced with the option to generating all of the random number combinations at once.
