werwhat? two bugs

What's going on here?

Where did my linebreaks go and where did the p come from?

In a sidenote, why doesn't

| > random(10000000000000000); | (3) Result: 694383321

work as expected, when

| > random(100000000000000000000000000000); | (2) Result: 1637481850962819326860743609

does?
