What is this tool?

This is a pseudo-random number generator that picks numbers from a range using the PHP gmp_random_range() function. Since it uses the PHP GMP mathematical extension it can generate very large integers up to hundreds of digits long.

To use it, select how many numbers to output and the minimum and maximum range from which to get random numbers. You can also choose whether to allow/disallow duplicate numbers in the output and if only odd or even random numbers should be picked.

The default output format for the numbers is to separate each one with a space character, but you can also use newline, comma or no space formatting.
