Having an issue with the input type. my contract has a function that sends token and has parameters of address and value. now the value is solidity data type of unit256 which is a number but in ethers.js it does not allow FLOAT as a number. which is right by literals. However, I want to be able to send FLOAT as a value. 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.
