I am unfortunately still very much a noob. Not just on Linuxcnc but also to Linux in general.

How did you make the upside down double quotes or ".  I couldn't duplicate that.

I believe the quotes depend on the location setting.
It should work with either ' ' or " " quotes.

[edit]
To get rid of all the zeros you could try:

echo ${1%.*}
case ${1%.*}

Okay. That makes sense.
 

Yes I am in Germany sorry for the strange quotation marks.
, and as I pointed out this looks like a float int problem. You try to compare an intern with a float, and that doesn‘t work
Aciera already pointed you into the right direction try this

#!/bin/bash
P = ${1%.*}
Q = ${2%.*} # in case you want to use the second parameter to
echo " P: ${P} Q: ${Q}";

case $P in
1) echo „case true“
halcmd setp classicladder.0.in-50 true ;;
esac
exit 0

as soon as everything work you can remove or comment the echos. This is my stupid way of debugging

I tried the new suggested code  and unfortunately it didn't work for me.
I think Linuxcnc has the M100 through M199 specifically coded to just
pass through the P and Q floats to a hal component and wont let you
use them in case, or if statement arguments.

I use around 20 different bash written m codes with if or case statements it works.

I also have a debug m code that uses zenity to show the p and q.

I don’t have Access to my machines now. So I can’t attach them. But if can read german you’ll find some at barn.works in my blog entries for the mill conversion
