String on ETH value input

[evandroguedes]

Hi fellows,

I would like to contribute here and found a possible issue on the ETH value input (Lookup Bar).

I noticed that it's accepting any character in the end of the value:

Is that the suppose way to work?

I can open a PR fix with unit tests, I just need to understand a little more about the needs. :)
