### 4/5 — Great! Just Needs Vice Versa

*2021-04-03*

Im a network administrator and I can easily convert to binary. However, having a tool like this would very much help to quicken the process and require a-lot less from me! I enjoy the apps functionality, but what I needed was the ability to input a number, for example 128, and receive back the binary translation. If this calculator worked the other way around, it would get an instant 5 star from me! Tremendous work! just needs that little update!

**Developer response:** Hello KoaBloom,

Thanks for the suggestion! Version 2 of TwoBaseTen now supports decimal to binary conversion. Let us know what you think of it!
