I have and old(ish) C# method I wrote that takes a number and converts it to any base: string ConvertToBase(int number, char[] baseChars); It's not all that super speedy and neat. Is there a goo...

Given two numbers P and Q in decimal. Find all bases such that P in those bases ends with the decimal representation of Q. #include <bits/stdc++.h> using namespace std; void convert10to...

According to Apache Commons Lang's documentation for StringUtils.isNumeric(), the String '१२३' is numeric. Since I believed this might be a mistake in the documentation, I ran tests to verify the...

How to convert a long number in base 10 to base 9 without converting to string ?
