Hello community.

Kindly consider:

| n i r |

n := ( 2 ** 256 ) - 1 .�� "the largest 256-bit value"

i := ( 0 to: n ) .�� "the interval 0 to 2**256-1"

"Produce three sets of computed test results."

3 timesRepeat: [

�� ��Transcript show: ( r := i atRandom ) ; cr .

�� ��Transcript show: ( r asByteArray hex ) ; cr . ]

According to comments in Pharo library code, atRandom fails for integer magnitudes greater than 2**30 .�� A reason for this limitation is not given, and it's not clear to a novice such as myself why the computed result of atRandom is permitted to sometimes be in conflict with the semantics of atRandom .

Can anyone provide a basic explanation of the rationale for a 'broken' atRandom ?

Alternatively, is this a known bug?

Thanks.
