I want to implement 4.pow(0.5)

[VasilGrozdanov]

Hey, I'm looking for the updated version of this question, since the library has changed since then. Also I'm wondering if it's going to be the same for 4.pow(1.5)

Hey @VasilGrozdanov! You can do that calculation like this now (using PRBMath v4.1.0):

pragma solidity >=0.8.19;

import { UD60x18, ud } from "@prb/math/src/UD60x18.sol"; // v4.1.0

contract Demo {
    function demo() external pure returns (UD60x18 result) {
        UD60x18 base = ud(4e18);
        UD60x18 exp = ud(5e17);
        result = base.pow(exp);
    }
}

Thank you very much :)
