This used to be true.

But with more recent versions of Blitz the values are 32-bit.

Edit: I've just tested this with Blitz3D 1.85 and it looks like random numbers have changed.

Open in online IDE
For k = 1 To 10
	n = Rand(-2100000000,2100000000)
	DebugLog Bin(n)
Next
Stop

This produces:

10000000110100010010100101101100
01111110100110001101000000101000
10000001000010010001101001111000
10000000100010100000000111111000
01111111100010111000110100000100
01111110110101100111101101000000

10000010110001101111101001001010
01111111010110011111101000110100

These are 32-bit values.

But those bits sure don't look sufficiently random.
I see far too many large blocks of 000000... and 111111...

And here's the output from BlitzPlus 1.37

What's with all those zeroes on the right?
