Lua script: Convert currency to number

Question

I'm a bit new to Lua, and trying to convert currency to a number. I tried tonumber() but that doesn't seem to be working.

How would I get Lua to convert a value like "$1,000" to "1000"?

Thanks!

You can use tonumber you just need to remove the formatting from the string first.

local str = "$1,000"
str = str:gsub(',','')
str = str:gsub('%$','') -- the `%` is needed to escape the `$`

local num = tonumber(str)
print(num == 1000)
