Big F_____ Number

Structure to help you store, represent and operate on very big numbers in Unity. This one separates coefficient from it's exponent (and prefers engineering notation at that).

---

Define "big numbers"

It's a Double with auxiliary Int64 exponent.

BFN.MaxValue = Double.MaxValue * Math.Pow( 10d , Int64.MaxValue );// +1.7976931348623157 E+9223372036854776115
BFN.MinValue = Double.MinValue * Math.Pow( 10d , Int64.MinValue );// -1.7976931348623157 E-9223372036854775500

These numbers are large enough to make most software refuse to calculate them and just print "infinity" or "invalid input".

Limitations

Coefficient is a Double so this is a lossy format. If you need lossless data type then you probably may want to go with System.Numerics.BigInteger.

Can I see it in the Inspector window serialized there?

Yes:

using UnityEngine;
public class BFN_ExampleComponent : MonoBehaviour
{
	[SerializeField] BFN _myBigNumber = new BFN( 11.2423085208 , 21 );
	void Start ()
	{
		Debug.Log($"my number is: {_myBigNumber}");
	}
}

Will produce this Inpector view:

"▼" button will help you simplify numbers for shorter notation ({ num=5000 , e=0 } -> { num=5 , e=3 }). Although coefficient will become longer sometimes because BFN prefers engineering notation ( { num=1 , e=5 } -> { num=100 , e=3 }).

• "F_____" stands for "double-precision floating-point"
