General consensus is that we would rather remove hex support than add support for binary and octal. ------------------------------------------------------------------------ [2013-10-31 16:43:09] cmbecker69 at gmx dot de | This is bugged also for hex numbers: The results are as expected according to the documentation. Note, that a hexadecimal number is only reported as being numeric, if it is in hexadecimal string notation (i.e. starting with 0x). The first example is correctly reported as being numeric, because the "e" is recognized as starting the exponential part of the number. ------------------------------------------------------------------------ [2013-10-31 16:08:45] daniele dot didomizio at eurac dot edu This is bugged also for hex numbers: print "526e948280122 " .(is_numeric("526e948280122") ?
