how remove numcheck
as code
for (var i:int = 0; i < 100000000;i++ ){
var a:Number = arr[0]
}
js code
for (var /** @type {number} */ i = 0; i < 100000000; i++) {
var /** @type {number} */ a = Number(this.arr[0]);
}
and how remove the Number(this.arr[0]);
this good,but not good in loop

it is need too many code，matrix3d.as rawdata 100+as number.and the float32array，and vector no need the check

I could be wrong, but I'm pretty sure the compiler should try to insert a
coercion there, because otherwise the JS code would behave differently
than the AS code if there were strings in the array.
The FalconJX compiler allows certain "directives" like
@flexjsignorecoercion to control coercions since they can be wasteful.
The following:
/**
* @flexjsignorecoercion Number
*/
public function numberarr():void
{
var arr:Array;
var n:Number;
n = arr[0] as Number;
}
was cross-compiled to:
/**
* @flexjsignorecoercion Number
* @export
*/
VectorObject.prototype.numberarr = function() {
var /** @type {Array} */ arr;
var /** @type {number} */ n;
n = arr[0];
};
Isn't that what you want?

Please file a bug. We might be able to use: @implements

It is probably because we don't have a way to specify the type of []
access.

i have add the -js-output-optimization=skipAsCoercions,and the number() are

Many folks have a different opinion. Their code may be counting on
implicit type conversions.
We have provided several options to control output. Besides
@flexjsignorecoercion, which should also work at the file level (but there
might be a bug there), there are new mxmlc options like
-js-output-optimization=skipAsCoercions which will ignore EVERY "as"
coercion in your code.

the float32array also has this issue.

Re: how remove numcheck

is it other way?
this var n:number = arr[i];
look good
but the as Number not too good.
or other option?

Maybe try:
var a:Number = arr[0] as Number;
I would add @flexjsignorecoercion Number to an asdoc block for the method.
Another option may be to convert arr to Vector.<Number>
