WebSolidity internally allows tuple types, i.e. a list of objects of potentially different types whose number is a constant at compile-time. Those tuples can be used to return multiple values at the same time. These can then either be assigned to newly declared variables or to pre-existing variables (or LValues in general). WebApr 5, 2024 · Keep in mind that there are no floats in Solidity. Therefore most tokens adopt 18 decimals and will return the total supply and other results as followed 1000000000000000000 for 1 token. Not every token has 18 decimals and this is something you really need to watch for when dealing with tokens. WebAug 1, 2024 · Solidity presents two bytes types : fixed-sized byte arrays: bytesN.
