extract number with seperated point in a string ruby

Question

How to extract a point separated number format from a string?

for example a string like this

a = 'ProductX credit 1.000'

how to to get only the 1.000 from that string?

Thank you kindly

See stackoverflow.com/questions/13706706/…, the regex .match(/\d+.\d+/) is probably the most reliable way, but it also depends on the concrete formatting of the strings and different languages may use different separators (in German it would be , instead of .). — Bruno E.

What's the format of the "number" you want to extract? Is it always one digit followed by a . followed by three digits? How do (much) larger or smaller numbers look like? What about negative values? — Stefan

You can use method split by space in ruby

a = 'ProductX credit 1.000'
a.split(" ").last

Result

"1.000"

The OP said the string was just an example. What if the number doesn't come last?

That extracts the last word, not necessarily "a point separated number"

You are right. Once you read this comment, I will delete my answer.
