Each ERC20 token has a different divisibility factor which is specified in the token contract. This value is usually 1,000,000,000,000,000,000 (1018) units (which means that most tokens can accept a value up to 18 decimal places), but can vary from token to token. Please check the client constants to see the number of decimal places the token supports.
