I am passing a unsigned 64 bit integer as the upper limit to random and receiving "(random: error in source expression), char 4"

put random(18446744073709551615) into _random

What is the max random can take?

Hi Kevin,

The max value for an argument of the random function is 2^32-1. Don't ask me why, this was a choice made by RunRev.

Best,

Mark

I think it's simply that for some functions like random(), baseconvert() and the bitwise operators, the engine converts values to 4 byte unsigned integers.

Best,

Mark Smith

And why doe the engine convert values to 4 byte unsigned integers, Mark? ;-)

I could tell you, but then I'd have to kill you

Efficiency, maybe?
