Using Flash'sMathobject, you can round to the nearest whole number using theMath.roundcommand. You may, however, prefer to round to different decimal places. This TechNote offers a technique for rounding to a specified decimal place.
Rounding to the hundredth decimal
Rounding to the nearest decimal simply involves inserting code in the Actions panel, as follows:
|1||Open your movie in Flash.|
|2||Select a Frame or an Instance.|
|3||Choose Windows > Panels > Actions.|
|4||Add this ActionScript in your Actions Panel to round to the hundredth decimal place, replacing yourNumber with the value you would like to round:
How the code works
The number used in the example below is 20 divided by 7, which equates to 2.857142857142857.
|int(20/7)returns the value of 2 by removing the decimal places off the number created by the calculation in parentheses so that it appears as a whole number.|
|Multiplying that result by 100 gives 285.
Note: This is due to the fact that theintfunction does not erase the decimals; it just does not show them.
|Dividing 285 by 100 gives 2.85. You have now rounded to the nearest hundredth.|
Rounding to other decimal places
If you prefer to round to a decimal other than to the hundredth, you can easily modify the code. Below are examples of code that will round (20/7) to different decimals:
|Code||Number of Decimal Places||Example Results|
|value= int((20/7)*10000)/10000;||4||2.85 71|
