karate match valuea == valueb MINUS a value from the Examples section sometimes doesn't work

I start off by extracting the 'amount' from the json response. (This is the originalBalance) After performing another action I then extract the 'amount' from another json response. (This is the newBalance).

I am then doing a match to check that the newBalance equals the originalBalance minus (from Examples) as shown here:

* def originalBalance = $response.giftCards[0].balanceAmount.amount
* def newBalance = $response.giftCards[0].balanceAmount.amount

And match newBalance == originalBalance - <amountToDeduct>
    
Examples:
     | amountToDeduct|
     | 0.01 |

Most times I run this it works fine. But other times it fails with a message similar to this:

match failed: EQUALS $ | not equal (NUMBER:NUMBER) 124.95 124.94999999999999

The two values that are being extracted from the json response are ok so there must be something going wrong with this line:

And match newBalance == originalBalance - <amountToDeduct>

Any idea what I am doing wrong?
