It sounds like that number is being treated as a floating-point value,

rather than as an integer. (Computers can express integers precisely, but

floating-point values are always approximations.)


For "How can I convert a float to an integer?" then in Flash 4 we used the

floor function of:

  int(value);


In the current version the model is JavaScript, so the standard Math.floor

function is used:

  Math.floor(value);


These functions truncate to the lowest integer... 2.97 will go down to 2.

In this case the goal is to round rather than truncate, and the usual way

is to add .5 to the value for rounding.  Try this:

   displayField = Math.floor(value + .5);


This will convert a floating-point value to the nearest integer for display.
