Problem Description:

Doc of RandRange says "If the numbers are not in the range -2,147,483,648 - 2,147,483,647, ColdFusion generates an error." but testing such edge case returns unexpected result.

Steps to Reproduce:

A:  #randrange(-2147483648, 2147483647) #
B:  #randrange(0, 2147483647)#

Actual Result:

A:  -2147483648
B:  (some random negative number)

Expected Result:

A:  some random number in between MIN_INT and MAX_INT
B:  some random number between 0 and MAX_INT

Any Workarounds:

Ridiculously convert UUID from createUUID() into binary and then into a number?

It has been 6 years, that should be enough time.

The fix for this bug is available as part of the early-access build for ColdFusion 2016 Update 2.
