regex to capture only number at the end

Question

I've some sample text as below.

this is 1989 representing text 245
this is sample text 235
this is 234 sample text with comma seperator 345,756

here i need a regex to get number only at the end, I've tried the below

[(0-9)+]

but this is capturing all the numbers, but only the number after the text ends needs to be captured.

The captured values should be

245
235
345,756

please let me know how can i do this.

Thanks

Answer 1

Isn't this much simpler ?

Allowed: only digits

\d+$

Allowed: digits, comma, dashes

[\d,-]+$

Allowed: digits, dashes

[\d-]+$

Answer 2

You can also try this which is simple to read :
^.*[0-9]+$

^.* Begins with whatever you want of whatever length
[0-9]+$ Ends with at least one number (or more)

If you wish only to recover the numbers and not the lines that correspond to your request :
[0-9]+$

And here we can add the complexity of recovering the comma :
[0-9]+(,[0-9]+)?$

Answer 3

You can use

\d+(?=[-, \d]*$)

Demo

Answer 4

You can do it as:

/[\d,]+$/mg

DEMO

To allow more characters, just add them to the character class:

/[\d,.-_]+$/mg

or if you want, simply allow everything except non accented letters:

/[^a-zA-Z]+$/mg
