Base Converter is a simple utility which converts between Decimal, Hex, Octal, Binary, and BCD. It also converts numeric values or characters to/from ASCII, Unicode, and UTF8. Updates are live, as you type, so there is a minimum amount of touches to get your result. In the "Char" field: If you input a character, Base Converter will return the ASCII (if available), Unicode, and UTF8 values. In the other fields, depending on the ASCII/Unicode/UTF8 setting, you can enter a value and the proper ASCII, Unicode, or UTF8 character will be returned. ## Key features - Decimal, Hex, Octal, Binary conversion - ASCII, Unicode, UTF8 conversion - Numeric to character conversion - Character to numeric conversion - Live, real-time updates - Simple utility interface ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/base-converter/id289256328/reviews.md ### 5/5 — Awesome *2012-09-10* Has everything I need for conversions. ### 1/5 — CRASH *2011-02-06* I have 1.8 installed. Crashes every time. Unusable. ### 3/5 — No fractional representation... *2009-08-27* I like the functionality, but there isn't a way to represent fractions (ie 4.1 = four and one tenth). Therefore, this looses two stars. Amend the problem, and it will deserve 5. ### 5/5 — Exactly what I needed! *2009-08-17* This app is the modern, digital implimentation of the old school IBM green and yellow base translation cards. It is simple, complete, and delivers a rainbow of accurate translation data with the absolute minimum investment of my time and attention to the app itself that is possible to achieve. Using a calc app to replicate the functionality of this app makes about as much sense as using your head to beat open a vault door..... ### 5/5 — Great utility *2009-02-05* Better than a clunky calc type application by providing the required data on a single page and calculating the result for all number systems at the same time. The simplicity of the interface vs. the amount of data delivered is also a breath of fresh air, enter the number and get your answer, what could be better! If there is intent for this app to develop further, I might ask that some basic functions could be added. For example it might be nice to be able to get a quick one's or two's compliment on the entered number with another a single button press. Not sure how you could cram this on a single page, but maybe another page for the bitwise math functions or something. Anyway, great app and well worth the .99! ## Frequently asked questions about Base Converter ### What number bases can Base Converter convert between?
