Constant folding issue with floats in mcs

Steps to Reproduce

1. Compile test case with mcs and run
2. Notice the floating point constants emitted by the compiler

using System;

public class Foo
{
	public static void Main()
	{
		Console.WriteLine((1.7f - 0.2f) % 1.5f);
		Console.WriteLine((1.5f) % 1.5f);
	}
}

IL from mcs compiled exe

    .method public static hidebysig 
           default void Main ()  cil managed 
    {
        // Method begins at RVA 0x2058
        .entrypoint
        // Code size 21 (0x15)
        .maxstack 8
        IL_0000:  ldc.r4 4.4703483581542969e-08
        IL_0005:  call void class [mscorlib]System.Console::WriteLine(float32)
        IL_000a:  ldc.r4 0.
        IL_000f:  call void class [mscorlib]System.Console::WriteLine(float32)
        IL_0014:  ret 
    } // end of method Foo::Main
