php trader_ema(Exponential Moving Average in php) function leading zero's float

I would like to use the PHP trader_ema function. However the input of a array with a leading zero's resultants in zero. Example:

realArray = array(0.0000002,0.000004,0.00005,0.00003);
var_dump(trader_ema ( $realArray, 2 )); 

//Output: 
array(5) { [1]=> float(0) [2]=> float(0) [3]=> float(0) [4]=> float(0) }

I think the problem is that PHP stores it's float into the array with scientific notation. But after searching I haven't found a solution yet. Any ideas?

Try setting up this option:

ini_set('trader.real_precision', '8');
var_dump(trader_ema(array(0.0000002, 0.000004, 0.00005, 0.00003), 2 ));

output:

array(3) {
  [1]=>
  float(2.1E-6)
  [2]=>
  float(3.403E-5)
  [3]=>
  float(3.134E-5)
}
