A random number generator performs some long operation on a randSeed value,
then returns everything after the decimal.

:rand()
:Func
:function(randSeed)->randSeed
:fPart(randSeed)->randValue
:Return randValue
:EndFunc

Where randSeed is a global variable like errornum.

If you set the randSeed to be the same on two different calcs -- in BASIC
<someNumber> -> rand() -- then yes, each rand() will produce matching
output.
