Problem with custom M code was created by Leo90

Hi all. I need help with my custom M code I've started to write. I ran into a problem right at the beginning with an "if" statement. My M code should be M105 P100 and it seems the "P" value isn't transfered into the M code.

#!/bin/bash

operand="$1"

if [[ "$operand" == 100 ]]; then
    halcmd setp lcec.0.EL2008.dout-0 true
    echo "ok"
else
    halcmd setp lcec.0.EL2008.dout-1 true
    exit 1
fi

exit 0

The M code always outputs "else" condition so "operand" isn't 100 as expected.

I also wrote a similar M code with "case" and there the P value is recognised by bash.

What did I do wrong here?

Problem is that $1 contains a float which bash can't handle, so try:

if [[ ${operand%\.*} -eq 100 ]]; then
