Round just seems to be always rounding up. Number format seems to be rounding either up or down depending on the value of the number before the decimal point. In my php.ini I have changed precision = 14. Reproduce code: --------------- echo "round 0.045 = " . round(0.045, 2) . "<br>"; echo "number format 0.045 = " . number_format(0.045, 2) . "<br><br>"; echo "round 0.055 = " . round(0.055, 2) . "<br>"; echo "number format 0.055 = " . number_format(0.055, 2) . "<br><br>"; echo "round 5.045 = " . round(5.045, 2) . "<br>"; echo "number format 5.045 = " . number_format(5.045, 2) . "<br><br>"; echo "round 5.055 = " . round(5.055, 2) . "<br>"; echo "number format 5.055 = " . number_format(5.055, 2) . "<br><br>"; echo "round 3.025 = " . round(3.025, 2) . "<br>"; echo "number format 3.025 = " . number_format(3.025, 2) . "<br><br>"; echo "round 4.025 = " . round(4.025, 2) . "<br>"; echo "number format 4.025 = " . number_format(4.025, 2) . "<br><br>"; Actual result: -------------- round 0.045 = 0.05 number format 0.045 = 0.05 round 0.055 = 0.06 number format 0.055 = 0.06 round 5.045 = 5.05 number format 5.045 = 5.04 round 5.055 = 5.06 number format 5.055 = 5.05 round 3.025 = 3.03 number format 3.025 = 3.02 round 4.025 = 4.03 number format 4.025 = 4.03 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=25694&edit=1
