Code

public function evaluate($other, $description = '', $returnResult = FALSE) {
  if (is_double($this->value) && is_double($other) && !is_infinite($this->value) && !is_infinite($other) && !is_nan($this->value) && !is_nan($other)) {
    $success = abs($this->value - $other) < self::EPSILON;
  }
  else {
    $success = $this->value === $other;
  }
  if ($returnResult) {
    return $success;
  }
  if (!$success) {
    $f = NULL;

    // if both values are strings, make sure a diff is generated
    if (is_string($this->value) && is_string($other)) {
      $f = new PHPUnit_Framework_ComparisonFailure($this->value, $other, $this->value, $other);
    }
