drawing float in pygame blit

Question

I have a problem with:

screen.blit(tile, [(x*tilewidth) - CAMERA.x +(WIDTH/2) , (y*tileheight) - CAMERA.y + (HEIGHT/2)])

screen.blit(object.image, [object.x - CAMERA.x +(WIDTH/2), object.y - CAMERA.y + (HEIGHT/2)])

The code above generates an error:

DeprecationWarning: an integer is required (got type float).  Implicit conversion to integers using __int__ is deprecated and may be removed in a future version of Python.
  screen.blit(tile, [(x*tilewidth) - CAMERA.x +(WIDTH/2) , (y*tileheight) - CAMERA.y + (HEIGHT/2)])

The program starts but then crashes due to an error. How do I fix this?

`WIDTH/2` results in a float. Try integer division: `WIDTH // 2` — 001, Aug 14 '20 at 12:25

round the cooridantes to integral values:

~~screen.blit(tile, [(x*tilewidth) - CAMERA.x +(WIDTH/2) , (y*tileheight) - CAMERA.y + (HEIGHT/2)])~~

screen.blit(tile, 
    [round(x*tilewidth - CAMERA.x + WIDTH/2), round(y*tileheight - CAMERA.y + HEIGHT/2)])

or use the // (floor division) operator (this only works if all the variables have integral values):

screen.blit(tile, 
    [x*tilewidth - CAMERA.x + WIDTH//2, y*tileheight - CAMERA.y + HEIGHT//2])
