In Flash 9, I get this for the traces: 2.3 0.2999999999999998 0.3 false false true
Good old-fashioned floating point precision error. Instead of testing if they are equal, You could test if the difference between them is very small, e.g.: trace(Math.abs(num2 - num3) < 0.00001); // true On 12/6/06, Doug Coning <[EMAIL PROTECTED]> wrote:
I'm scratching my head over this. Not sure what I'm doing wrong? I need to compare a decimal value of a numeric field to see if it contains a specific value of 0.3. Here is some sample code: var num:Number = 2.3; var num2:Number = num - int(num); var num3:Number = 0.3; trace(num); // 2.3 trace(num2); // 0.3 trace(num3); // 0.3 trace(num2 == num3);// false trace(num2 > num3);// false trace(num2 < num3);// true Why doesn't 0.3 equal 0.3? I've replaced int with Math.floor(), and it still doesn't work. I need to get the value after the decimal point and see if it equals 0.3. Thanks for your help.
