When i input this: log(0.125) + 4log(20.5) + 0.5log(4), its answer is -5*10-12 instead of 0, the same problem when i input : log(X) - ln(X)/ln(10), the answer should be 0 but it shows different answer: Y*10-12 (X and Y are number) it seems like there're some problem with the logarithm funtion or the memory. The other funtions work fine (i think!)
Is there any way to fix this??

P/s: I got it 6 years ago

Your calculator is ok. Due to the accuracy of the used algorithm and the number
of the internal digits the answer of a calculation may be not exactly as expected.
