Question - Code Image Scale Problem - Possible Bug?

First, want to say I love the updates within GMS 2. My current project has benefited immensely from the updates, and I'm excited to keep using it.

However, I believe I have run into a possible bug for the room editor or the built-in image_scale variables. Within the room editor, I set the image_yscale variable to '1.4' for a certain object.

However, I opened the debug menu and discovered the object's 'image_yscale' value was running at roughly '1.3999999'. This has oddly caused some unexpected results within my game when relying on the image_scale variables.

See the included image for visual evidence.

My question - Is this a bug within GMS 2? Or something else?

Version Details
I'm using Game Maker Studio v2.0.3.56 on a Windows 10 PC.

Might be a floating point accuracy issue. I believe internal variables are stored as single-precision rather than double-precision like other variables. Try using round() instead.

I have found a fix by using the sprite's height value instead. However, this still seemed like odd, and probably not intentional, behavior.

I don't recall ever experiencing it with GMS 1.4. However, it is possible I just never noticed.
