The bug

If you specify a min_distance field in a sound definition without including a decimal point, the field is completely ignored with no error or warning. Other fields like pitch work just fine.

How to reproduce

1. Download and open the attached world
2. Use the two command blocks
Expected result: They should sound identical
Actual result: The one on the left is quieter because its max_distance field was ignored

Sound file

For reference, here is the sound_definitions.json file. integer completely ignores the max_distance because it's set to 50 instead of 50.0.

{
   "format_version": "1.14.0",
   "sound_definitions": {
      "integer": {
         "category": "neutral",
         "max_distance": 50,
         "sounds": [
            {
               "name": "sounds/unique1"
            }
         ]
      },
      "float": {
         "category": "neutral",
         "max_distance": 50.0,
         "sounds": [
            {
               "name": "sounds/unique2"
            }
         ]
      }
   }
}
