Move the approxDiff heuristic from the sc unnamed namespace to rtl::math and disable floating-point contraction (FMA) for this function. On ARM64 (Apple Silicon), the use of Fused Multiply-Add (FMA) results in higher intermediate precision during floating-point operations. While mathematically more accurate, this prevents legacy rounding heuristics in approxDiff and approxValue from detecting and cleaning rounding artifacts in series generation (e.g., 1.1 - 1.0). Disabling fp-contract forces intermediate rounding to 64-bit IEEE 754 limits. This ensures the noise expected by the approximation logic is present, restoring consistency with x86-64 behavior and fixing issues where values like 6.0 are incorrectly rendered as 6.00000000000001.
