My application must produce exactly the same numeric results on all machines. I understand that float/double math in C# is not deterministic, but how about the binary representation of literal values?
float x = 1.23f;
How will 1.23f be stored in the compiled DLL file? As a binary representation of 32-bit IEEE-754 format float? Or as some intermediate representation that will need converting to IEEE-754 floating point by the jitter on target machine (a potential source of indeterminism)?
I understand why floating point operations in C# are not deterministic. I am asking ONLY whether the binary representation of literals is deterministic. Please, no answers about floating point determinism in general.
They are stored as IEEE 754 format.
You can verify this by using ILDASM.EXE to disassemble the generated code and inspecting the binary values.
For example, float x = 1.23f; will generate:
IL_0000: /* 22 | A4709D3F */ ldc.r4 1.23
(Note that this is stored in little-endian format on Intel platforms.)
