Solidity Trigonometry Solidity library offering basic trigonometry functions where inputs and outputs are integers. Inputs are specified in radians scaled by 1e18, and similarly outputs are scaled by 1e18. Each invocation of the sin() and cos() functions cost around 1600–1700 gas (see the testNoReverts costs in .gas-snapshot for more info). This implementation is based off the Solidity trigonometry library written by Lefteris Karapetsas which can be found here. Compared to Lefteris' implementation,...
