Dear Sage Developpers, Great Job on the new release of sage 6.10 yesterday. I tried some doctesting for some some code I had which was running fine on sage 5.9 and notice the following issue :
Sage 6.10 produces the following incorrect Output for the .numerator() function call sage: u00,u01,u10,u11,a10=var('u00,u01,u10,u11,a10') sage: (a10 + u10/u00 - u01*u10^2/(u00^2*(u01*u10/u00 - u11)) + u10*u11/(u00*(u01*u10/u00 - u11))).numerator() a10*u00^2*u01*u10 - a10*u00^3*u11 sage: (u10/u00 - u01*u10^2/(u00^2*(u01*u10/u00 - u11)) + u10*u11/(u00*(u01*u10/u00 - u11))).is_zero() True Where as Sage 6.9 produced the following correct output for the .numerator() function call sage: u00,u01,u10,u11,a10=var('u00,u01,u10,u11,a10') sage: (a10 + u10/u00 - u01*u10^2/(u00^2*(u01*u10/u00 - u11)) + u10*u11/(u00*(u01*u10/u00 - u11))).numerator() a10 sage: (u10/u00 - u01*u10^2/(u00^2*(u01*u10/u00 - u11)) + u10*u11/(u00*(u01*u10/u00 - u11))).is_zero() True I tried on this on 3 separate machine compilation of sage 6.10 and the same issue creeps up. I could use advice on work around this bug if it is well known. Thanks in advance, Keep up the great work!
