Math.Log, Log10. The Math class provides logarithms. With the Math.Log and Math.Log10 methods in the System namespace, we compute logarithms with a specific base or base 10.
These methods are tested—they do not need to be debugged. If you need to optimize their performance, try using a lookup table to cache or precompute the most common values.
Finally You can duplicate the effects of Log10 with Log by passing 10 as the second argument.
using System;
class Program
{
static void Main()
{
double a = Math.Log(1);
Console.WriteLine(a);
// Ten to the power of 3 is 1000.double b = Math.Log10(1000);
Console.WriteLine(b);
double c = Math.Log(1000, 10);
Console.WriteLine(c);
}

Uses. These methods are used for scientific formulas. Developing a fractal generator in the C# language would be interesting, and it would involve logarithms.
Summary. The Math.Log and Math.Log10 methods provide accurate results for logarithms in the C# language. They are built into .NET—they can be used directly.
