Dear all,

I use GiNaC to perform analytic calculation, but when I try to use .numer() and .denom() methods, I get a wrong result.

1. expr.numer()/expr.denom() is not always equal to the original expression!!!

2. Using .numer_denom() method could always get the correct answer.

I attach a simple code source file and logger file to check that problem. The logger file will be different when you run the code on your computer.

Yours,

Yang
