• [PR] Use serialize_precision for printing floats in var_dump() — , float var_dump() (0.1 + 0.2 === 0.30000000000000004):

  
  // 
  $sum = 0.1 + 0.2;
  var_dump($sum); // float(0.3)
  var_dump($sum == 0.3); // bool(false) WTF???
  
  // 
  $sum = 0.1 + 0.2;
  var_dump($sum); // float(0.30000000000000004)
  var_dump($sum == 0.3); // bool(false) Makes sense...
