ee593c2673 bug fixes, move the faster serialisation into the numeric header
serialisation ends up roughly 2x improvement going from sstream to snprintf

Run on (4 X 3500 MHz CPU s)
CPU Caches:
  L1 Data 32K (x4)
  L1 Instruction 32K (x4)
  L2 Unified 262K (x4)
  L3 Unified 6291K (x1)

e183e37ae6 remove roundoff test, add test for exponential representations
-- testing that a number with >15 significant digits rounded off to 15 failed on all tested platforms

1003ba507d Add a test for serialize_number_to_string
-- should allow serialisation of up to 15 significant digits
-- don't use default stringstreams, typically only get ~6 significant digits
