BigReal
An arbitrary size and precision rational number stored using two BigIntegers.
Usage
Create from fixed-size numbers:
Console.WriteLine(new BigReal(100)); // 100
Console.WriteLine((BigReal)3.14); // 3.14
Console.WriteLine(new BigReal(4, 3).ToString(4)); // 1.3333
Perform basic operations:
Console.WriteLine((BigReal)3 * (BigReal)5); // 15
Console.WriteLine(BigReal.Pow(3.4, 2)); // 11.56
Parse from string:
Console.WriteLine(BigReal.Parse("12.34")); // 12.34
Console.WriteLine(BigReal.Parse("2e2.5").ToString(2)); // 632.45
Trigonometry:
Console.WriteLine(BigReal.Sin(100).ToString(20)); // -0.50636564110975879365
Performance
Basic operations comparing BigReal, BigDecimal, and BigFloat:
Add:10 + 3Divide:10 / 3DivideToString:(10 / 3).ToString()
