FullMath
Facilitates multiplication and division that can have overflow of an intermediate value without any loss of precision
Handles "phantom overflow" i.e., allows multiplication and division where an intermediate value overflows 256 bits
Functions
mulDiv
Calculates floor(a×b÷denominator) with full precision. Throws if result overflows a uint256 or denominator == 0
