16.726--5.670--25.129**16.312--5.718--22.847**14.366--5.258--25.545**16.920--3.457--25.425**19.419--6.712--25.198**18.536--7.602--25.240**19.152--5.518--24.957**15.501--7.808--24.644**16.883--6.024--27.528**

I have to split the numbers. Remove those ** and -- between numbers and store in single variable( $points ). I have to do this in perl. i have provided the code till removing of ** between the numbers.

output of $points  : 16.726 5.670 25.129 16.312 5.718 22.847 14.366 5.258 25.545 16.920 3.457 25.425 19.419 6.712 25.198 18.536 7.602 25.240 19.152 5.518 24.957 15.501 7.808 24.644 16.883 6.024 27.528

Thanks in advance.

Что я уже пробовал:

$points = "16.726--5.670--25.129**16.312--5.718--22.847**14.366--5.258--25.545**16.920--3.457--25.425**19.419--6.712--25.198**18.536--7.602--25.240**19.152--5.518--24.957**15.501--7.808--24.644**16.883--6.024--27.528**";
@pointss = split(/\*\*/,$points);
print "@pointss\n";
