# TValue Examples

This notebook demonstrates the usage of `TValue`, the fundamental data structure in QuanTAlib.

For detailed documentation, see [TValue.md](TValue.md).

#!csharp

// Reference the library
#r "..\..\bin\QuanTAlib.dll"

using System;
using QuanTAlib;

## Creating TValue

You can create a `TValue` using `DateTime` or `ticks`.

#!csharp

// Using DateTime
var now = DateTime.UtcNow;
var val1 = new TValue(now, 100.5);
Console.WriteLine($"Created TValue: Time={val1.AsDateTime}, Value={val1.Value}");

// Using Ticks
long ticks = now.AddMinutes(1).Ticks;
var val2 = new TValue(ticks, 101.0);
Console.WriteLine($"Created TValue: Time={val2.AsDateTime}, Value={val2.Value}");

#!markdown

## Implicit Conversions

`TValue` supports implicit conversions to `double` and `DateTime` for convenience.

#!csharp

double d = val1; // Implicitly gets Value
DateTime t = val1; // Implicitly gets Time (as DateTime)

Console.WriteLine($"Double: {d}");
Console.WriteLine($"DateTime: {t}");

// Arithmetic operations using implicit conversion
double result = val1 + 5.0;
Console.WriteLine($"Result (100.5 + 5.0): {result}");

## Immutability

`TValue` is immutable. You cannot change its properties after creation.

#!csharp

// val1.Value = 200; // Error: Property or indexer 'TValue.Value' cannot be assigned to -- it is read only

// To "change" a value, create a new instance
var val3 = new TValue(val1.Time, 200.0);
Console.WriteLine($"New TValue: {val3.Value}");
