Is there any easy way to calculate the area of each class not using Int, reclassify and raster to polygon

convenient?  The quickest with the least amount of programming knowledge.... and given the appearance of your data ... would be to 'int' it so that you get a table.  If this yields too many classes for a table to be generated, then a reclass to an integer scale would be the 2nd quickest since this would be guaranteed to produce an integer raster, a table, a cell count... which multiplied by cell area (cell size squared) will give you the area of each class.
