Double replacement for numbers that go over 1e308

breakinfinity.cs's Issues

Parsing of different styles of scientific notation

The only format which is acceptable now is 1e308

The formats that are throwing exceptions:

• 1E308
• 1E+308
• 1e+308
• e308
• e+308

Some things that don't work in Unity/C# 6.0

1. you can't do 'other is BigDouble bigDouble'. you have to replace it with a separate is and a cast later. happens in Equals and CompareTo
2. 'Random' is ambiguous between System.Random and UnityEngine.Random. fix by changing it to 'private static readonly System.Random Random = new System.Random();'
3. you can't do 'out var formatDigits'. have to separately declare int formatDigits and then out to it.

based on a conversation with Wild Obunga in #modification on AD server. since a primary reason to make this library is for use in Unity games, this seems pretty important to do.

How can I find a %?

I'm trying to use a bigdouble number in a progress bar but it might not be possible? I wanted to do something like this:

BigDouble num1 = 1000;
BigDouble num2 = 100;

BigDouble num3 = (num2 / num1) * 100;

int num4 = Convert.ToInt32(num3);
hp1.Value = num4;
hp1.Maximum = 100;

Is this even possible? I tried converting it to a string and then back, but the number gets too large.

• If possible, would you mind showing me how? Thank you!

Crash in Language Indonesia

There is a crash happened in Indonesia(Language) on Android when I called BigDouble.ToString() , I guess it caused by the defferent expression between Indonesia and others . By the way I found the 'formatprovider' is unused in BigNumber.FormatBigDouble(BigDouble value, string format, IFormatProvider formatProvider).

NotImplementedException: The method or operation is not implemented.

Hello
And I wanted to start adding numbers popped up error NotImplementedException: the method or operation is not implemented.
BreakInfinity.BigDouble.op_Explicit (BreakInfinity.BigDouble v)
and it doesn't add or display anything anywhere.
Here when I click on the error
public static explicit operator float(BigDouble v)
{
throw new NotImplementedException();
}

Number incorrectly hits Infinity.

Number goes to Infinity after stage 5144. What am I doing wrong?

    public static BigDouble CalcEnemyHealth(int stage)
    {
        BigDouble x = BigDouble.Pow(1.35, Mathf.Min(stage - 1, 65));
        BigDouble y = BigDouble.Pow(1.15, Mathf.Max(stage - 65, 0));

        Debug.Log(y.ToString("E3"));

        return BigDouble.Multiply(15, BigDouble.Multiply(x, y));
    }

Stage 5143 will display 1.674E+308 here but stage 5144 will display NaNE+0. The returned value will show Infinity at stage 5144.

> comparison operator doesn't work when comparing finite number with exponent greater than 0 to positive infinity.

I am implementing a cap on a value using BigInteger.Min, using PositiveInfinity to essentially mean "no cap". However, I found that when the value reached 10 (which changed the exponent), Min would return that Infinity was the smaller value!

Min defers to the > operator, and the exponent for infinity is actually 0, where the line which perform the comparison is this:
if (a.Mantissa > 0) return b.Mantissa < 0 || a.Exponent > b.Exponent;
where a = 10 and b = Infinity.
Since the mantissa of a is 1 and larger than 0, the comparison is b.Mantissa < 0 (false) || a.Exponent (1) > b.Exponent (0) or false || true, thus, Infinity is smaller than 10.

Add custom Unity editor

BigDouble Array/List doesn't work in the editor

When setting up a BigDouble[] array SerializedField in a ScriptableObject, the inspector doesn't properly render the list, as shown below:

[SerializeField] public BigDouble[] CostList;

This is happening in Unity 2021.21f.

Any help will be greatly appreciated.

Create UPM package

Exponential ToString() formatting returns 'e+' instead of 'E+'

It's not a big deal but it's contrary to the readme.

Add [Serializable] attribute

I don't think you need to do anything else, since it should serialize fine by default

Max value of BreakInfinity.cs is actually 1e(9e18) rather than 1e(9e15)

Not really a big issue just more of an FYI since the readme only talks about the max of 1e(9e15) despite it going higher.
The MAX_SAFE_INTEGER for JavaScript is 9,007,199,254,740,991, but in C#, it uses a long, 9,223,372,036,854,775,807 which just has 3 more digits.
This means the max is around 9.99e9,223,372,036,854,775,806 (1 exponent below from infinity) or more simply, 1e(9e18)

Exponent might be wrong

While trying out this package I noticed that the exponents don't seem to be working as expected. Typing '1000' into the left field in the Unity Inspector yields a value of 1e6, and typing '1000000' (1 million) yields a value of 1e21. I would imagine the expected values should be 1e3 and 1e6, respectively.

License?

What is the license of this?
