Ether and gas units

Why use this example

Use this pattern to confirm Solidity arithmetic and unit behavior before putting the same expression into a contract. The entry isolates ether and gas units so its input, result, and state changes stay easy to compare.

Solidity to run

uint256 amount = 1 ether

amount
amount / 1 gwei
amount * 5 / 100

What to expect

The run exposes 1 ether in wei, its value in gwei, and the integer result of calculating five percent.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
