Description of the bug

The EWW_RAM.used_mem magic variable cannot be used in formatbytes without being cast to an int through floor/ceil, which is inconsistent with the other memory magics that return bytes as integers

Reproducing the issue

This will happily display available mem, but error for used mem.

(defwindow example
           :monitor 0
           :geometry (geometry :x 0 :y 0 :anchor "top center")
           :stacking "fg" :windowtype "dock"
           (box :orientation "horizontal"
                "used_mem: ${formatbytes(EWW_RAM.used_mem, true, 'iec')}"
                "|"
                "available_mem: ${formatbytes(EWW_RAM.available_mem, true, 'iec')}"))

Expected behaviour

Expected this to work
"${formatbytes(EWW_RAM.used_mem, true, 'iec'}"
like this does
"${formatbytes(EWW_RAM.available_mem, true, 'iec')}"

Additional context

Error output:

error: Failed to turn 15014653952.0 into a value of type i64
┌─ /home/USER/.config/eww/eww.yuck:52:30
│
52 │ "${formatbytes(EWW_RAM.used_mem, true, 'iec')}"

Other memory information uses the sysinfo crate and it looks like that returns u64's, while used_mem explicitly casts them to f32 to do its subtraction.

just came to report this myself, i got around it with {formatbytes(replace(EWW_RAM.used_mem, ".0", ""))}

floor/ceil might be a better way to do it though... XD
