Functions

• add

  function add(uint256 a, uint256 b) internal pure returns (uint256)

  Adds two numbers, reverts on overflow.Parameters:a - uint256b - uint256Returns:uint256

• div

  function div(uint256 a, uint256 b) internal pure returns (uint256)

  Integer division of two numbers truncating the quotient, reverts on division by zero.Parameters:a - uint256b - uint256Returns:uint256

• mod

  function mod(uint256 a, uint256 b) internal pure returns (uint256)

  Divides two numbers and returns the remainder (unsigned integer modulo), reverts when dividing by zero.Parameters:a - uint256b - uint256Returns:uint256

• mul

  function mul(uint256 a, uint256 b) internal pure returns (uint256)

  Multiplies two numbers, reverts on overflow.Parameters:a - uint256b - uint256Returns:uint256

• sub

  function sub(uint256 a, uint256 b) internal pure returns (uint256)

  Subtracts two numbers, reverts on overflow (i.e. if subtrahend is greater than minuend).Parameters:a - uint256b - uint256Returns:uint256
