I can’t reproduce this. there are many seed values that also generate values close to 1, like 985675

Hi,

Thanks for it, I use it with the nextDouble() method and it appear that the first call to this method always return a value near zero, with a lot of different seed.

Have you ever note this problem?

An issue?

Thanks!

Thanks, I was trying hard to figure out how to do this! Very useful and easy to use.

Found the issue! I *was* going mad, but I’ll write it up here in case anyone is having the same problem.

I was using the standard Flash AS3 Math.random to generate the seed for your PR - and that’s time-based! So adding trace statements made it load slower, which in turn changed everything else. Or rather, *not* adding trace statement caused it to generate the same numbers over again, which I thought was the PRNG’s doing, but really wasn’t. How strange!

maybe a compiler bug, who knows. if you can reproduce the problem with a few lines drop me a note.
