説明

Version Used:

<PackageReference Include="Microsoft.CodeAnalysis.CSharp" Version="4.11.0" PrivateAssets="all" /> <PackageReference Include="Microsoft.CodeAnalysis.Analyzers" Version="3.11.0" PrivateAssets="all" />

Steps to Reproduce:

  1. Use ToCSharpString on any TypedConstant that represents a float

Expected Behavior:

It produces a string that represents the float and could be used to initialise a new float in C#, i.e., 0.5f

Actual Behavior:

It produces a string without a type suffix, i.e., 0.5

Use case:

I'm creating a source generator that generates source code based on NamedArguments in AttributeData. When the named argument's value is retrieved, I use arg[x].Value.ToCSharpString() to turn the value into a string to place in the generated code and the string being generated for floats is causing compile errors
