How can I make it so my textbox can allow negative number
currently im using:
:gsub('[^%d.]', '')
Also I have been trying to find threads related to this, but I can’t understand. Sorry if this sounds dumb.
You would just include "%-". The percent sign is there because the dash has a special meaning in string patterns, so by putting a % in front of it you are cancelling out that meaning so that it is matched as an actual - sign.
"[^%d%.%-]"
By the way the period is a magic character as well so you have to escape it there too.
