## Questions

### Why does the value not change when I paste a very long number?

Because it should not. This converter works on the digits rather than through a floating-point number, so a 64-bit value keeps every digit — which is the whole reason to use it instead of a calculator.

### How are values above 9 written in base 36?

With the letters A–Z after the digits, so 35 is Z and 36 is 10.
