In which case "123foo" is 123e-15 (femto). If we are going to have all these postfixes, then we would probably want invalid ones to evaluate to NaN instead of truncating them. We can always have a standard fn/method that strips the invalid characters off the end if the string: my $string = "1.23Ki4b2XXX". my $a = +string; # NaN my $b = +$string.numeric_prefix; # 1230 + 16i my $c = +$string.real_prefix; # 1230 my $d = +$string.integer_prefix; # 1 or some such thing.
