WebCore Compiler Error

WEB TMS WEB Core
1

If I specify a constant with a small value (say 1e-6) the value comes out as 1e-7. I know you don't believe me. Frankly I don't believe me .... but here is a demo project to show this. On a new WebCore application I added a few labels and a button and then defined a constant and showed the constant and some calculations using it. See code snippet below:

var
Form1: TForm1;

const
SmallConstant = 1e-6;

implementation

{$R *.dfm}

procedure TForm1.btn_ShowResultsClick(Sender: TObject);
var val : Double;
begin
l_ReadValue.Caption := Format('%g',[SmallConstant]);
l_CalcedVal.Caption := Format('%g',[SmallConstant*1000000]);
val := SmallConstant;
l_ValValue.Caption := FloatToStr(val);
end;

And the results:

Looks like a pas2js compiler bug.
We'll report it to the pas2js team. Thanks.

We investigated this further and found it only has the issue when the constant is set to 1e-6. On the other hand, if we set a variable and assign value 1e-6 to the variable, and it also has no issue.

We also attached a demo project if you would like to take a look.

pas2js team already fixed the compiler.
This updated compiler will be in the TMS WEB Core v2.1 release.

Hey Bruno, a quick question, any idea when version 2.1 will be released? thanks!~

We're working extremely hard on getting everything finished asap.
This week or next week.

Thanks Bruno for the time and effort! We tested it on 2.1 and it works well.
