(12C) Check if given number is Prime Number or not

[Gamo]

I have try program from Dieter version and this one run much faster very nice program.

With this program I test one prime number to real HP-12C, Emulator for 12C and 12C Platinum

The prime number is 9,000,000,001

Result on:

Real 12C answer 0 [X<>Y] 2

Emulator 12C answer 0 [X<>Y] 2

Emulator 12C Platinum 1 X<>Y 9,000,000,001

Is this another rounding problem on the 12C ?

Thank You
