You've got it right in the Real case, although you might want f[x_?NumericQ] instead. If by 'boolean variable' you mean one that has values in {True, False}, then this will do the trick: f[x_?(MemberQ[{True, False}, #] &)] ----- Selwyn Hollis http://www.appliedsymbols.com (edit reply-to to reply) On Nov 26, 2004, at 1:04 AM, JMyers6761 wrote: > All, > I would like to define a function wich would work (in different ways) > for both > real and boolean input argruments.
