Hello

Regex is used to capture text with a consistent pattern.

If you need to capture the discount percentage in a string like this:

Discount percentage: 18%
Total cost: $56

Once you obtain the amount you could calculate an amount sure.

As per @varunk’s post, please provide:

  • Sample
  • Expected output
  • Tell us what is consistent about the sample

You will have an answer soon after posting :smiley:

Hi,
I know what REGEX is, I used it a lot to check if a variable contains letters/numbers, etc.
My question is how to use REGEX to calculate a discount.
For example:
The original amount is: $ 90
Discount is: 30%
How to do the calculation by REGEX.
It can be done in another way by:
(Original amount) * (100 / (100-discount)) Example: 0.7 * 90 then the return is the amount after discount.
Thanks
