shader language declaring multiple floats?

Question

I am trying to understand this shader: https://godotshaders.com/shader/2d-liquid-fill-inside-sphere/

The shader is using a weird format where it says float and then the code on the next line is indented, with each line divided by a comma.

Just to make sure: The indent is just for readability and all that this means is that multiple float variables are being created? For example, in the screenshot, the float variables sdf, vB and vBA are creted?

Answer 1

It's a standard C syntax for declaring multiple variables.
Note that C doesn't care for whitespace, including newlines. So for example this is perfectly valid C code:

for
(int i 
	=0
	;i< 
		100; i
++){
				}

Unrelated to your question, but it could be helpful to check out the shadertoy it mentions in the comments, as that shader explains some of the variable names (and adds AA)
