[Tanat05]

There is a bug in which 455 appears as True.
I don't know if that's a curse word because I don't speak English, but what does it mean if that's a curse word?

[Prabesh01]

since 4 is mapped to A and 5 is mapped to S, 445 becomes ass. hence True.

the mapping is done to detect profanity written in leet. to fix it, we can let valid integers and float pass through. or there might be other better ways to do it.
