We measure time-integrated CP-violating asymmetries of neutral charmed mesons in the modes D{sup 0}{yields}K{sup -}K{sup +} and D{sup 0}{yields}{pi}{sup -}{pi}{sup +} with the highest precision to date by using D{sup 0}{yields}K{sup -}{pi}{sup +} decays to correct detector asymmetries. An analysis of 385.8 fb{sup -1} of data collected with the BABAR detector yields values of a{sub CP}{sup KK}=(0.00{+-}0.34(stat){+-}0.13(syst))% and a{sub CP}{sup {pi}}{sup {pi}}=(-0.24{+-}0.52(stat){+-}0.22(syst))%, which agree with standard model predictions.
