Hi
I always seem to have difficulty with pattern matching in Lua, here is another example that has stumped me so far
I am trying to trim a number string to remove non significant trailing zeros. So for example
"123.450000000" = "123.45"
"1234500" = "1234500"
"12345.00" = "12345.0"
I could of course write a function that iterates through the string from the back dropping zeros, but I thought there is probably a more elegant solution using Lua pattern matching functions.
Can this be done neatly with pattern matching ? Thanks for any suggested code snippets
Regards Geoff
