About base converter
Hex, decimal, binary and UTF-8 text, converted through a single big-integer representation so nothing overflows at 2⁵³ the way naive JavaScript conversions do. Useful for reading bytes32 values, decoding string constants out of contract storage, and checking that a number you were given in one base is the number you think it is.
