See {IERC20-approve}. Requirements: - spender
cannot be the zero address.

decimals()
function decimals() external view returns (uint8)
Returns the number of decimals used to get its user representation. For example, if decimals
equals 2
, a balance of 505
tokens should be displayed to a user as 5.05
(505 / 10 ** 2
). Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the value {ERC20} uses, unless this function is overridden; NOTE: This information is only used for display purposes: it in no way affects any of the arithmetic of the contract, including {IERC20-balanceOf} and {IERC20-transfer}.
Returns
Name | Type | Description |
---|---|---|
_0 | uint8 | undefined |
decreaseAllowance(address,uint256)
function decreaseAllowance(address spender, uint256 subtractedValue) external nonpayable returns (bool)

cannot be the zero address. - spender
must have allowance for the caller of at least subtractedValue
.
