v2.0.0

Added

• Addition and subtraction functions in the typed libraries.
• Gas estimates for fromInt, fromUint, pow, toInt and toUInt.
• Structs PRBMath.SD59x18 and PRBMath.UD60x18, simple wrappers to indicate that the variables are fixed-point numbers.
• Typed versions of the library: PRBMathSD59x18Typed.sol and PRBMathUD60x18Typed.sol.

Changed

• Increase the accuracy of exp2 by using the 192.64-bit format instead of 128.128-bit.
• Rename PRBMathCommon.sol to PRBMath.sol.
• Set named parameter instead of returning result in pow functions.
• Update gas estimates for exp and exp2.

Fixed

• Bug in log10 which made the result incorrect when the input was not a multiple of 10.
• Typos in NatSpec comments.

v1.1.0 [YANKED]

Added

• New convertor functions fromInt and toInt in PRBMathSD59x18.sol.
• New convertor functions fromUint and toUint in PRBMathUD60x18.sol.
• New function mulDivSigned in PRBMathCommon.sol.
• New function pow in PRBMathSD59x18.sol and PRBMathUD60x18.sol

Changed

• Rename the previous pow function to powu.
• Speed up exp2 by simplifying the integer part calculations.
• Use the fixed-point format in NatSpec comments.

Fixed

• Minor typos in NatSpec comments.

v1.0.5

Added
