Often, you’ll want to be able to divide your tokens into arbitrary amounts: say, if you own 5 GLD, you may want to send 1.5 GLD to a friend, and keep 3.5 GLD to yourself. Unfortunately, Solidity and the EVM do not support this behavior: only integer (whole) numbers can be used, which poses an issue. You may send 1 or 2 tokens, but not 1.5.
To work around this, ERC20[1] provides a decimals[2] field, which is used to specify how many decimal places a token has. To be able to transfer 1.5 GLD, decimals must be at least 1, since that number has a single decimal place.
How can this be achieved? It’s actually very simple: a token contract can use larger integer values, so that a balance of 50 will represent 5 GLD, a transfer of 15 will correspond to 1.5 GLD being sent, and so on.
