Convert Python floating-point into C# decimal

I'm trying to convert a floating-point number in Python into decimal in C# using pythonnet.

Let's say there is one number 0.0234337688540165776476565071.

I have tried this in two ways:

1. using float()

   from System import Decimal
   Decimal(0.0234337688540165776476565071)
   # Same with Decimal(float(0.0234337688540165776476565071))
   
   0.02343377
   

2. using native Python Decimal

   from System import Decimal
   from decimal import Decimal as PyDecimal
   Decimal(PyDecimal("0.0234337688540165776476565071"))
   
   # This loses every number under the floating-point
   0
   

What should I do?

From the examples in your question, it looks like you are trying to convert a string to System.Decimal. For that, System.Decimal has a Parse method:

from System import Decimal

Decimal.Parse("0.0234337688540165776476565071")

Note: you probably also need to pass CultureInfo.InvariantCulture depending on your scenario.
