Suppress scientific notation in Haxe across targets

[Jason Sturges]

Is there a way to suppress scientific notation in Haxe?

For example, if I have:

var f:Float = 0.00007075;
var s:String = Std.string(f);

In targets such as html5, this outputs: 0.00007075

However, c++ targets output: 7.075e-05

Is there a way to control whether scientific notation is used for string format?

You need to use some formatting function. thx.format has one here: https://github.com/fponticelli/thx.format/blob/master/src/thx/format/NumberFormat.hx

You can change the global output mode for floats on cpp using an extern like:

class Test
{
  @:native("__hxcpp_set_float_format") @:extern
  static function setFloatFormat(format:String):Void { }
 
  public static function main()
  {
    trace(0.00005);
    trace(5e20);
    setFloatFormat("%.12f");
    trace(0.00005);
    trace(5e20);
  }


}

You can only use the standard printf formats, and the change is global, so it may not be what you want.

Thanks to you both.

That native extern is very cool; though, I wish I could apply different formats in a single trace statement when outputting multiple variables on a single line.

Actually disregard - the native extern is perfect.  Exactly what I hoped for.  Thanks, again.
