toFixed rounds, not floors ! bug 24711 is not a Bug !! (1.95) . toFixed( 1 ) = 2.0 because: Math.round ( 1.95 * 10 ) / 10 equal 2

All browsers before returns string value (IE, Opera, Konqueror, Chrome, Firefox) rounding a Number.

yep, this is a dupe. ieee754(.95) < decimal(.95), hence rounds up to 0.9 (ecma-262 15.7.4.5 requires we select the nearest value). ieee754(9.5) == decimal(9.5), hence rounds up to 10 (ecma-262 15.7.4.5 requires we select the larger to two equally near values). *** This bug has been marked as a duplicate of bug 24711 ***
