Abstract: In this study, we calculated the dependence of thermodynamic observables, namely, pressure, baryon number density, and baryon susceptibility, on the baryon chemical potential ${\ensuremath{\mu}}_{B}$ through lattice quantum chromodynamics using the canonical approach. We compare the results with those obtained using the multiparameter reweighting (MPR) method. The results of these methods were found to be in very good agreement in the regions where the errors of the MPR method are under control. The canonical method yields reliable results up to ${\ensuremath{\mu}}_{B}/T=3$, where $T$ is the temperature. Multiple precision operations play important roles in the evaluation of canonical partition functions.
