- // Advantages:
- // - Input gets closest value
- // - Output emits string that when read yields identical value.
- // - Handles Infinity and NaNs (but not re-readable).
- // Disadvantages of dtoa:
- // - May not work for all double formats.
- // - Big chunck of code.
- // - Not reentrant - uses atatic variables freelist,
- // result, result_k in dtoa
- // (plus initializes p5s, HOWORD, and LOWORD).
