And so does NetRexx.<br>
But should it not raise error as PL/I does?--[[User:Walterpachl|Walterpachl]] ([[User talk:Walterpachl|talk]]) 09:53, 6 November 2013 (UTC)
:It depends upon that which you are doing with it:
::a**b=c is the inverse function of log(c base b) = a - there is no such thing as log base 0 and no number has a log of zero in any base.
::Number Theory dealing with polynomials (which are themselves numbers) any number ** 0 is 1 by definition.
::Calculus treats it as undefined.
