// Both variants come with absolute error bounds and a reversibility and monotonicity
// guarantee (see test driver code below). They should pass D3D10 conformance testing
// (not that you can verify this, but still). They are verified against a clean reference
// implementation provided below, and the test driver checks all floats exhaustively.

// 
// half_to_float_fast: table based
// tables could be done in a more compact fashion (in particular, can store tab2 in low word of tab1!)
// but something of a dead end since not very SIMD-friendly. pretty much abandoned at this point.
//
// half_to_float_fast2: use FP adder hardware to deal with denormals.
