ActionScript Math.abs() Conditional Not Working

i have a number variable, vx, that is changing with an enter frame event. in the enter frame fu开发者_C百科nction i have the following code:

if  (Math.abs(vx) <= 0.05);
    {
    trace(Math.abs(vx));
    }

immediately, it's starts outputting numbers that are well above 0.05:

does this make sense to anyone?

You have an extra colon ';' after your if.

if (Math.abs(vx) <= 0.05);<--

Without i think it will works better:

if  (Math.abs(vx) <= 0.05) {
 trace(Math.abs(vx));
}
