I assume you want to say that it also works for seeds ≤ 0.
Replace ex with x² and you got one of the classic PRNGs for programmable calculators.

It generates integers between 0 and 999998.

This can test to see the Randomness result.

?!? – how do you test the statistical properties this way?

Would like to get the range between
100,000 to 999,999

If you got a random number r between 0 and 0,9999... you can easily transform it into a random integer between a and b (inclusive) by calculating int((b–a+1)*r) + a. So if you want an interval from 100000 to 999999 the transformation is int(900000*r)+100000, as grsbanks already noted.
