(12C) Check if two numbers is to the power of other

[Gamo]

Sorry my bad forgot to explain of the problem.
For 12C Platinum on Android I put exactly the same program steps with step numbers like 09 for 12C and 009 for 12C Platinum.
Program run but always return 0 display eventhough
it is true and all the store registers result are correct answer.

Example:
Is 5 to the power of 25

5 ENTER 25 R/S

Display 0 // suppose to be display 1

Correct answer in registers
R1 is 5
R3 is 2
R2 is 25

Remark: 12C Platinum on PC work fine.
