HP 12c Platinum Error 0 in Percent Difference

[Gamo]

I try this problem and see no issue.

Example: 35.5 to 31.25 What is the percent change?

--------------------------------------------

RPN mode

35.5 [ENTER] 31.25 [∆%] --> -11.97

--------------------------------------------

ALG mode

35.5 [=] 31.25 [∆%] --> -11.97

--------------------------------------------

For people who getting used to the RPN logic sometime
get confuse on how to perform functions on ALG mode.
