Since the dawn of time, developers have constantly asked themselves the following questions: What is 42 in Binary? What about in Hex? And in Octal? What's the hex and decimal ASCII code for the letter 'G'? Is 2B OR NOT 2B equal to 3F or to FF? And to get the answer, they had to install all sorts of apps, cause there was no single, all-in-one solution. Not any more! inBinary allows you to quickly convert numbers between the four most common numbering systems (Decimal, Binary, Hexadecimal and Octal) And to look-up any ASCII (printable) character by HEX code, Decimal value (DEC) or even Symbol It can also calculate the following operations: * NOT * AND * OR * XOR * NAND * NOR On any two numbers in any base (yes, any base you can think of between base-2 and base-16, it even works for base-13). And what's best is that inBinary has: * ABSOLUTELY NO ADS * ABSOLUTELY NO ANALYTICS Thank you for reading this far :-) Enjoy inBinary
