One more comment on the subject. As we were trying to solve a Sturm-Lioville boundary value problem by finite difference method, we calculated eigenvalues and eigenvectors of some matrices on matlab and mathematica. In both of the programs, their 32 bit and 64 bit results were different (we tried t
