Intro

this is a repo that use 2 BigInteger that represent a fraction

when calculate it manipulate on BigInteger (thus numerator/denominator) when transcribe out, it calculate and output the number.

it use a heap allocation represent a number, as if ensure a number is not truncate by IEEE standard.

Struct

public readonly struct Fraction
{
	private readonly BigInteger num;
	private readonly BigInteger den;
}

Manipulation / Calculation

Fraction a = 1;
a /= 3;

Features

1. it auto (implicit) convert the type of any Integer Type into Fraction

2. it auto (implicit) convert the type of any Double Type into Fraction

but Double Type only record the first 15 digit (valid) which may cause issues.

Mode

• it always keep the number in fraction mode which is percise.
• when calculate the number still in percise mode, which do as numerator and denominator.
• when print it into none percise mode, it will calculate into specific digit.

Operators

1. [operator] {var} >> {int}, this operator let you get percise digit number of a fraction.
2. [operator] ! {var} , this operator simplify the fraction.
3. [operator] ~ {var} , this operator try turning the fraction into a complex fraction.

Fraction a = 52163;
a /= 16604;
Console.WriteLine(a >> 20); // (3, 14159238737653577451)
Console.WriteLine(a >> 50); // (3, 14159238737653577451216574319441098530474584437484)
Console.WriteLine(~a); // (3, 2351 / 16604)
Console.WriteLine(!a); // 52163 / 16604

Tricks

• when add into Fraction mode. in the VS, the operator will change color. hover the operator to see if it's correct.
