Python Fu - Math operations failing

[BaconWizard17]

Hi all,

I'm setting up a script, and part of it is to scale the image to a max size of 256 for one type of texture and a max size of 128 for a different type of texture. That aspect isn't working, so I isolated it into a separate script, and it's still not working. I've managed to figured out where the issue is happening, but not why. Here's the isolated code:

Code:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from gimpfu import*
   
def resizeMax(image, layer, texType):
   # Determine the max size based on the texture type:
   if texType == 0:
       # primary texture
       maxSize = 256
   else:
       # secondary texture
       maxSize = 128
   # Get the current dimensions of the image
   currentWidth = image.width
   currentHeight = image.height
   # Check which is bigger
   if currentWidth >= currentHeight:
       # Wide image or square
       scaleFactor = maxSize / currentWidth
       pdb.gimp_message("DEBUG: Scale Factor is")
       pdb.gimp_message(scaleFactor)
   else:
       # Tall image
       scaleFactor = maxSize / currentHeight
       pdb.gimp_message("DEBUG: Scale Factor is")
       pdb.gimp_message(scaleFactor)
   # Get the new sizes
   newWidth = scaleFactor * currentWidth
   newHeight = scaleFactor * currentHeight
   # scale the image accordingly
   pdb.gimp_image_scale(image, newWidth, newHeight)
   # Resize the layer to the image size
   pdb.gimp_layer_resize_to_image_size(layer)
   # Display the changes
   pdb.gimp_displays_flush()

def resizeMaxMain(image, layer):
   resizeMax(image, layer, 0)
   
register(
   "python_fu_test_resize_max",
   "",
   "",
   "BaconWizard17",
   "BaconWizard17",
   "January 2023",
   "Resize to Max Size",
   "*",
   [
       (PF_IMAGE, "image", "Input image", None),
       (PF_DRAWABLE, 'drawable', 'Layer, mask or channel', None)
   ],
   [],
   resizeMaxMain,
   menu='<Image>/Test'
)

main()

The issue is the line where the scaleFactor is being determined. For whatever reason, scaleFactor = int(maxSize) / int(currentWidth) is giving a value of 0, even though maxSize is nonzero (defined as 256) and currentWidth is also nonzero (512 in the image I was testing). I used pdb.gimp_message() to verify the values right before the operation, and they're what I expect. Maybe I'm doing the division wrong? I also tried converting maxSize and currentWidth to integers (with int()), but that didn't change anything either. Any thoughts would be appreciated.
