Yeah ur right about the eval. I did a triple head to head with ur regex and
eval/no eval. The eq without the eval demolishes all.
Rate eval RE noeval
eval 3397/s -- -87% -96% eval "$var" eq $var + 0;
RE 25253/s 643% -- -72% /^[-+]?(\d+(\.\d*)?|\.\d+)([eE][-+]?\d+)?$/
noeval 90909/s 2576% 260% -- $var eq $var + 0;
