Ionic/Capacitor Rounds HTML Canvas coordinates in XCode build, not in dev server

[andrew-lyons]

I am developing a capacitor plugin that requires floating point numbers from the client. I am using an HTML canvas and listening to the touch events associated.

When using ionic serve for the dev environment, my touchevent data looks like this:

12:38:06.813 Canvas.tsx:43 screenX :  762.3359375
12:38:06.813 Canvas.tsx:43 screenY :  756.05078125
12:38:06.813 Canvas.tsx:43 clientX :  201.3359375
12:38:06.813 Canvas.tsx:43 clientY :  585.05078125
12:38:06.813 Canvas.tsx:43 pageX :  201.3359375
12:38:06.813 Canvas.tsx:43 pageY :  585.05078125
12:38:06.814 Canvas.tsx:43 radiusX :  11.5
12:38:06.814 Canvas.tsx:43 radiusY :  11.5
12:38:06.814 Canvas.tsx:43 rotationAngle :  0
12:38:06.814 Canvas.tsx:43 force :  1

but in my XCode build, I log this:

⚡️  [log] - identifier :  1269311752
⚡️  [log] - clientX :  265
⚡️  [log] - clientY :  331
⚡️  [log] - pageX :  265
⚡️  [log] - pageY :  331
⚡️  [log] - screenX :  265
⚡️  [log] - screenY :  331
⚡️  [log] - radiusX :  21.15234375
⚡️  [log] - radiusY :  21.15234375
⚡️  [log] - rotationAngle :  0
⚡️  [log] - force :  0
⚡️  [log] - touchType :  direct
⚡️  [log] - altitudeAngle :  0
⚡️  [log] - azimuthAngle :  0

Notice the XCode results are integers, not floating point or doubles. I have no idea why this would be different between the dev environment and production build. Anyone have insights?

When you use ionic serve you mean you are running on desktop or you load the site on the phone?

I've added a touch listener to the body and on the iPhone I always get integers, doesn't matter if it's a website or a Capacitor app, while on desktop browsers and Android I get floating points.
