Calc: Calculate percentage change

Hi,

I don't get why Calc returns -100% for

         =(B1-A1)/ABS(A1)

if A1 and B1 are the same number?

I would expect result to be 0%.

[e.g. https://www.calculatorsoup.com/calculators/algebra/percent-change-calculator.php?v_1=245&v_2=245&action=solve]

Got it! Typo in formula. Sorry.
