Does it cost any gas to cast a bytes32 memory value to uint256? What is the assembly op code for this?
Does it cost more gas to use =, >, , < operations, so is that true with all types that support those operators? Or is the gas cost for these operators different depending on the type?
I tested some of these things in remix and got mixed results -- sometimes it cost more gas, sometimes less.
Does it make any sense to cast bytes32 to unint256 for doing an operation like this: `require(uint256(myvalue) != 0);`
If you know the answers to these, can you please tell me how you know?
