> "0 ** 0; result undefined " > Result of 0 ** 0 is defined, it #39;s 1. That #39;s all. In the strong mathematical sense 0 ** 0 is undefined. Defining 0 ** 0 as 1 violates continuity and sometimes may lead to false conclusions.
Nevertheless, if you disagree with that, you can always check operands to produce desirable result, for example: param a := (if x = 0 and y = 0 then 1 else x ** y); _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
