Force 2 digit

[admin]

You can simply use string.format:

Code:

val = 1
str = string.format('%02d', val) -- pad with 0 up to 2 chars in width

log(str) -- will log "01"

For converting number to a string you can either use Custom values or a table instead of multiple IFs:

Code:

values = {
  [1] = 'Value 1',
  [2] = 'Value 2',
  [3] = 'Value 3',
}

val = values[ 2 ]
log(val) -- will log "Value 2"
