PVS-Studio warning V636 for TinyCAD

void CContext::TextOut(....)
{
  int *actual_width = new int[len];
  double max_adjust = max_char_adjust;
  int iwidth;
  ....
  if (iwidth / actual_width[i] < 1.0 - max_adjust)
  ....
}

This suspicious code was found in TinyCAD project by PVS-Studio static code analyzer.
Warning message is:
V636 The 'iwidth / actual_width[i]' expression was implicitly casted from 'int' type to 'double' type. Consider utilizing an explicit type cast to avoid the loss of a fractional part. An example: double A = (double)(X) / Y;. context.cpp 712
