Did just what I needed at the time. Just one small problem. I needed to convert 11 to base 4, then try multiples like 11 x 1000, then 11 x 1234. Couldn't do it in the app so used phone's android calculator which returned an answer with a comma separating thousands. Pasted it into this app but the comma stopped it working. Neat little app but for most work I prefer the BASE function in Excel.
