QuadrupleLib

QuadrupleLib is a modern implementation of the IEEE 754 binary128 floating point number type for .NET 7 and above based on the UInt128 built-in. The goal of this project is to eventually create a fully fleshed out 128-bit floating point arithmetic library that includes all of the bells and whistles one could possibly want.

Project TODOs (Completed)

• Adheres to minimum requirements of IEEE 754 specification
• Partially implements .NET 7 INumber generic arithmetic interface
• Implements all basic arithmetic operations (+, -, *, /, %, ++, --)
• Implements all standard rounding functions (Round, Floor, Ceiling)
• Implements basic ToString and Parse/TryParse methods
• Implements conversion methods to & from binary64 type
• Provides conversion pathways to all standard .NET number types via binary64

Project TODOs (HELP WANTED!!)

• Unit tests to check for specification coverage
• Implements IEEERemainder as suggested in IEEE 754
• Implements typical library functions (Pow, Atan2, Log)
• Supports all rounding modes (atm only implements "ties to even" mode)
• Supports .NET Core formatting features for ToString and Parse
• Implements .NET 7 IBinaryFloatingPointIeee754 generic arithmetic interface
