Details

• Describe what you were trying to get done.

  I'm sorry it's me again with some weird low-level issue. I use a DLL where a function returns a System.Single. Its return value is 0.01. Before pythonnet version 3.0 this got converted to a Python float also of value 0.01. With Pythonnet 3.0 I get a Python float 0.009999999776482582 instead. I can reproduce this issue by creating System.Single objects.

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

  import clr
  import System
  
  # Parse a string to avoid conversion from Python float to dotnet
  print(System.Single.Parse('1e-2'))
  # Create a pure dotnet object without conversion back to Python (I think .ToString() gets called here?)
  print(System.Single(0.01))
  # Create a pure dotnet object without conversion back to Python and convert back to Python
  print(System.Single(0.01).MemberwiseClone())

  0.009999999776482582
  0.01
  0.009999999776482582
  

  With pythonnet 2.5.2 this will return

  0.01
  0.01
  0.01
