jsalling aa4d773df2 Tests for Printing All float values ...

Takes about 10 minutes to run all floats, so split into 3 tests for parallel
running later. This was useful during development for finding hard corner cases
and getting the routine to high quality. Off by default.
Note that all floats 16.0 and up can be represented uniquely (in this format) and will
round-trip back to the exact same float with sscanf(). This property is true for
UnityPrintFloat, despite a few rounding error cases, it will produce output identity.

Better comments and refactor on round ties to even
Add upper threshold value on round to even feature since numerical precision issues
start to give approximations when dividing one large double by another. When tested
on float values, using 1e22 gave the fewest rounding errors.

Fix warnings from gcc. Some float constants do not behave well in existing tests.
Add casts where conversions could be imprecise.

testparameterized.c

Finished fixing floating point comparisons. We have streamlined how floats and doubles are checked, but we still can't compare them for equality directly. So we're directly testing for infinite and NaN before checking diffs. Also, we've officially decided that for testing purposes NaN shall equal NaN, +Inf shall equal +Inf, and -Inf shall equal -Inf. It's what most people expect during a test.
