> 0:3fb:9999999999999 > 0:3fb:999999999999a I would like to note that 0.1 is a rational number and therefore its decimal representation is periodic: 0.10000...000... = 0.09999...999..., i.e. it is a repeating decimal. However, it cannot be represented as a finite fraction in a positional numeral system, whose base does not have prime factors 2 and 5 (since 10 = 2*5). _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
